A canny hunter and climbing the Austrostipas

On a recent nocturnal excursion into our front yard, a slightly odd little tuft on a Drooping Sheoak needle caught my eye. It looked just like a little bit of debris, but on close inspection, I saw that it was one of the most curious looking little predators, a Lacewing larva.

These little hunters carry tiny pebbles and bits of decaying vegetation on their backs for camouflage. You can see the mighty pincers on this little one on the right hand side. Aphids and other small invertebrates beware!

Elsewhere in our yard I found an adult Lacewing – I don’t know if they’re the same species, but the two images give an impression of the incredible transformation this little one will undergo.

Spear Grasses (Austrostipa) are flowering at our place at the moment. Whilst I will find their sharp-pointed, spring-curled-tailed seeds annoying as they collect pin-like in my socks and trousers in a month or two, when they are flowering, they are so beautiful.

They also look very beautiful through the macro lens

I’ve seen a few small beetles on the flower stalks, mostly dark and only a few millimetres long. On one tussock, I found quite a number of slightly larger beetles, about 5 mm long.

As they climbed and also descended, I got quite a good view of their undersides.

Back down again

This was the only Austrostipa tussock that I saw these beetles on and when they got to the top of a leaf, they seemed to get very confused about its ending, which made me think they really had intended to climb something different, perhaps something with a decent leaf to eat.

And what now?


The Golden Wattles in our bush are playing host to myriad small beetles at the moment and they are very active by night. I don’t know what species they are and can add no notes of particular interest, but I thought it worth posting some photos. Certainly some have awakened from their winter sleep in a mood for making more beetles.

I also found what I at first took to be a tiny (4mm) wasp on a flowering Rough Wattle. When I got a good look at the photos, I saw that it had a long tube mouth folded backwards under its thorax, which indicates that it is actually a bug. Bugs belong to the order hemiptera (half wing) so named as the front part of the wings are often hardened into a protective surface whilst the back half remains a soft membrane. I don’t know what this one is, but suspect it might be a seed bug (Lygaeid bug) nymph.

I’ve also been pleased to find a few Plume Moths. They are the most striking looking animals!

Of baby feet, baby insects and snoozing flies

The beautiful caterpillar that I posted a few days back has been hanging around on our Flax-lily and as I looked at it I become fascinated by its legs. Well, its prolegs really. Here’s the photo I posted last time.

The caterpillar again.

Being insects, caterpillars have six true legs. These are the three pairs right up the front near the head. The back five pairs of “legs” are prolegs. I was able to gently turn the flower stalk to get a better look and at 5:1 macro.

Two pairs of prolegs from below.

When I was trying to learn a bit more about these, I came across a very interesting explanation on a great site called the Caterpillar Lab. In short, caterpillars don’t use their true legs a lot. But the do use their prolegs, which vary in number between species. Not having a rigid body or internal pressure sacs for muscles to pull against, they grasp whatever they’re on with their prolegs and then contract the muscles in their body to pull themselves forward, detaching and reattaching their prolegs as they go. The little hairy projections on the feet of their prolegs grip the surface a bit like velcro. The pads also have receptors in plantar hairs to taste whatever it is the caterpillar is on.

Caterpillars are, of course, the babies of moths and caterpillars – hence the first part of the title. Larvae are young that don’t look at all like the adult and will undergo a dramatic metamorphosis to become an adult. Beetles also have larvae that look utterly different to the adult form. At present, there are a lot of black silky caterpillar-like creatures crawling across the ground. These are Soldier Beetle nymphs, which will feed in the leaf litter.

At the end of summer, this little one will look like this.

Nymphs are young that look a bit like the adult form and gradually change through different sheddings of skin – each new stage being called an instar.

Looking closely at a Drooping Sheoak in our yard, I found quite a few tiny nymphs of flat bugs. I have no idea what type of bug these are, but it’s easy to see the different instars in one photo. I’m keeping an eye on them to see how they develop.

Also on the Sheoak were are few Psyllid bugs. Some of these were in the process of mating.

I was very excited to find a large mite on a Grey Box in our bush. It looked very like a larger version of the Red Velvet Mites I’ve posted before, but not so velvety and not as vividly red. It turns out to be the delightfully named Rainbow Mite of the genus Rainbowia.

Rainbow Mite. “I like to eat Psyllids!”

They are indeed related to the Red Velvet Mite, but unlike its smaller cousin doesn’t feed in the leaf litter. It cruises around the eucalypts looking for Psyllid bugs to eat. They are arachnids and have eight legs, but unlike spiders have jaws to crunch up their prey. But why the name? Not so much for their vivid colour, it seems. According to the Queensland Museum web site, they are named for an arachnologist of the late nineteenth and early twentieth centuries – WJ Rainbow. What a wonderful name for both the mite and the arachnologist!

Powerful mouth parts for munching on psyllids.

I do like to photograph flies, but during the day they tend to be a bit skittish. There have been a lot sleeping on different grasses and plants in our bush by night, so I’ve managed a few pleasing shots. There are still very large numbers of very small flies only 2-3 millimetres long. These must be incredibly important pollinators for our native plants and I’m seeing a lot around by day, visiting a wide range of flowers.

Does a tiny fly have dreams as it sleeps?

At the other end of the scale, the Golden Blowfly is an imposing subject at 2:1 macro. Not everyone’s idea of beauty perhaps, but certainly fascinating to look at and a crucial player in our bush.

Timing, defenses refined by evolution

As spring unfolds, I’m seeing a lot of invertebrates around our place at Strangways that I’ve not seen since the end of autumn. Various species of wasp are around and most have been a bit camera shy, but one was happy to pose.

Brachonid wasp?

I think this little cutie is a Brachonid wasp, but I’m happy to be corrected. Other Brachonids are definitely waking up at the moment. The ovipositor on this one was just too long to include fully in the photo. Brachonids often use these to deposit their eggs into the bodies of Sawfly larvae that the wasp larvae will eat from inside. Over millenia of evolution, the timing of the emergence of the adult wasps has been perfected as I’m starting to find quite a few schools of Sawfly larvae munching on eucalypt leaves.

Sawfly larvae

These larvae have appeared on the same trees that I found adult Pergagrapta Sawflies last autumn, so I wonder if they are the same species.

Caterpillars are increasing in diversity. There are still a lot of Chlenias moth caterpillars about, but not as many as a few weeks ago when I posted about them. They have been joined by some other interesting caterpillars.

What am I looking at?

As I was inspecting a Grey Box sucker looking for subjects, I couldn’t help but notice one leaf stalk that seemed to be pointing the wrong way. As I watched, things started to change.

Not quite a leaf stem
What a disguise!

I have no idea what species this little caterpillar was, but I am lost in admiration for the camouflage.

Another very successful strategy for a juicy caterpillar is to look spiky and unappetising. This one was on a Black-anther Flax Lily flower stalk.

How not to look tasty!

Lacewings are also starting to appear in greater numbers and variety.

Green Lacewing

I always like looking at Hoverflies, with their elegant shapes and steady hovering flight. Lots of them are now investigating the flowers in the yard and bush. This one was very sedate, resting on a Groundsel and so a good photo was pretty easy.



Wolf spiders are also emerging from their holes in the ground. At night, their beautiful emerald eyes shine in the glow of my headlight. These spiders tend to carry their babies on their backs, which I’ve never managed to get a photo of. They still make an impressive subject for a close-up, in-your-face portrait.

Strange encounters on the tussocks

A wander into the grassy woodland at our place the other night led to some interesting encounters and a puzzle with a solution reminiscent of science fiction.

Focusing my attention on the Poa and Austrodanthonia grasses, I was impressed by how many invertebrates were either sleeping, feeding of hunting on them. And it seems that a lot of insects are waking from their winter down time. I was delighted to find a tiny Praying Mantis nymph, all of 15mm long.

I also found quite a few leafhopper nymphs.

One activity that I forgot to list was mating. A pair of moths were busy organising the next generation.

Tussock grasses seem to be a favourite spot for small flies and wasps to sleep.

Katydid nymphs are also starting to emerge. A Twig-mimicking Katydid (Zaprochilus) was doing its best to look inconspicuous.

When this nymph is an adult, its wings will project strikingly upwards from its thorax, looking like a forked twig. As a nymph, theu are tiny buds just discernible.

I found another Katydid nymph not far away.

Hanging on a silk thread between two grass strands, I found a fungus gnat with a large, swollen and very red abdomen. My guess is that she’s heavily pregnant, but would be happy to hear any more informed explanations.

Cup Moth larvae have started making their appearance.

On the ground, perhaps knocked off a wattle as I moved around, I found an exquisite green moth. I assumed it has a relationship with wattles or eucalypts, but I discovered that its a Native Cranberry Moth (Poecilasthena pulchraria) and its caterpillars feed on native cranberry bushes (Astroloma).

A small bug on one tussock looked to me like a Mirid Bug nymph.

Other larval forms about are, of course, caterpillars. Chlenias are still very abundant, but not in quite the enormous numbers of last week. I was puzzled that a small percentage of them seem to have small parcels stuck on their backs. One suggestion is that it might be the skin from a previous shedding that hasn’t come unstuck yet. I’d appreciate any thoughts.

Chlenias with a mystery parcel

Another caterpillar similar in size and shape to Chlenias was magnificently camouflaged.

I look like a stick too!

One fly that I found on a Golden Wattle leaf had me really puzzled. It didn’t look dead as its eyes were quite clean, but it was quite immobile and had a lot fuzz on its abdomen. Its wings and legs were in a very odd posture.

A puzzling fly

A bit of research led me to the fungus Entomophthora muscae, which as its name implies specialises in flies. When the spores come into contact with a fly, they have enzymes that break through the skin of the insect, allowing the fungal threads to spread through the fly. The fungus digests the organs of the fly and as the fly gets sicker, the fungus alters it’s brain function to make the hapless insect climb to a high point on a leaf, stretch its wings and legs. All of this sets the fly up perfectly for the next step. The fungus by now has spread microscopic canons over the abdomen and these will shoot spores out for them to land on the next victim. The wing and leg positions optimise the range of the spores.

And of course, where there are insects, there are those that eat them. Especially spiders. Like a baby Huntsman, about 10mm long.


Not Chlenias again!

I’ve done a couple of posts featuring the Chlenias moth caterpillars that abound in our bush at present. They are doing a great job participating (unwillingly) in the conversion of Cassinia into birds! A pair of Brown Thornbills have built a nest less than a metre from our front veranda at Strangways. They often make their nests close to our house as I think they realise that we will deter predators. And the number one food item they’re bringing in to their nestlings?

The parents seem quite happy to come in to the nest even when we’re on the veranda. The very disciplined young stay absolutely silent when they get their feed.

Quite a load of tucker!

A few years ago, I read of research that found that when predatory birds such as currawongs or magpies – and cuckoos – approached the nests of Brown Thornbills, the parents will mimic the hawk alarms of other bird species and this will frighten the predators away. Such clever little birds!

Currently building a nest only a few metres from the Thornbills’ nest is a pair of Superb Fairy-wrens. The nest is buried deep in a Hop Bush covered with native clematis. The wrens when they leave tend to go to the same spot on Grevillea with a Hardenbergia in the backgorund, which makes for a very photogenic setting.

Speckled Warblers are not uncommon at our place, but are often hard to see and get near to for a photo. I was pleased when I found myself in the path of a pair of them as they foraged in the leaf litter and fallen wood recently. They are of the same family as the Thornbills – Acanthizidae – which also includes gerygones and scrubwrens.

I’ll pocket the protection money, but my children will still eat you.

Lots of bugs that use their tube mouth parts to suck the sap of plants produce a sweet honeydew that attracts ants. In a (usually) win-win situation, the ants get some valued nutrition and the bug gets an entourage of stinging, biting friends to scare off predators.

I was very interested to find a Brown Lacewing (Micromus sp. I think) on a Grey Everlasting which at first I thought was eating a tiny aphid. I was surprised as I didn’t think adults would eat aphids. When I looked at the photos on the back of my camera, I could see it was getting honeydew from the rear end of the aphid.

Brown Lacewing and aphid

The Lacewing was handling the aphid quite roughly, grabbing the aphid with its front legs to make sure it could get to the anus and the sweet secretion.

A bit of rough handling.

Now I’m pretty sure that this wasn’t the win-win deal that the aphid would like as the Lacewing was not going to stick around to look after its little sweet acquaintance. Moreover, the Lacewing’s larvae are sure to be looking for little aphids just like this to dine on, as I photographed a few years back.

I posted a little while back about the Chlenias caterpillars feeding on Cassinia plants in our bush. We now seem to have hit peak caterpillar. It seems every Cassinia bush has at least 20 of these caterpillars, ranging in length from 10 to 50mm. They are also quite prevalent on Golden Wattles, but the Cassinia is really being stripped by them.

Chlenias on Golden Wattle

These caterpillars basically eat anything they land on. From what I’ve been able to find, the first instars of these caterpillars travel from their hatching site (which can be the leaf of any plant) by launching a balloon of silk to be carried by the wind. I wonder if the complex leaf structure of Cassinia catches them more efficiently and hence the heavier numbers. As we have a super-abundance of Cassinia at our place at present, I’m not too fussed about the caterpillars doing a bit of pruning as well as being fodder for our birds.

The view from below

Also still present in great abundance are Fungus Gnats. The more I see of these tiny flies, the more I recognise how essential they are for pollination, spreading fungal spores and as food.

Fungus Gnat on Golden Wattle

Whilst I was prowling around the Golden Wattle blooms at night, I was surprised to see tiny yellow grubs eating the flowers. They look a bit like yellow Ladybird larvae. I’m not sure of this and whether this species is always yellow or whether it borrows its colour from the flower as some Flower Spiders do.

Ladybird larva perhaps?

Our sleepy neighbour

In the 26 years we’ve had our place at Strangways, we’ve seen numerous species of lizards, but never a Shingleback (Tiliqua rugosa). So it was a pleasant surprise to see a very pale specimen appearing from under a ground cover in our front yard to sun itself.


I’ve read that Shinglebacks may be the lizard with the most common names in English – Stumpy-tailed, Bob-tailed, Bogeye, Sleepy Lizard and Pinecone Lizard amongst them. I learned from a wonderful episode of Off Track on ABC Radio National that they are the only lizards known to be monogamous and live for up to 30 years in the wild. If you haven’t heard this delightful show, make sure you click on the link and enjoy a fascinating 1/2 hour. I really only have one shot of this little cutie as it was so soporific that it just stayed still for a very long time.


Out of the moss

With the damp earth of winter, it is a joy to spend some time low to the ground and admiring the mosses in our bush. And admiring the things that com out of the moss.

In lots of places, Scented Sundews (Drosera whittakeri) push up through the mosses. It’s not a coincidence that nearby, mushroom fruiting bodies are also poking up.

Scented Sundews and Galerina fungus fruiting body emerge from the damp moss

Fungus gnat larvae feed on the fungus strands under the soil. At this time of year, adults will be laying eggs in the soil. I’ve also read that some fungus gnat adults will feed on the mushrooms themselves and carry the fungus spores around the bush. Sundews that happen to be amongst areas rich in fungi will get more gnats stuck to their sticky spines and will therefore be able to proliferate more.

As I was rolling around the ground trying to get good angles on the luxurious mossy floor of our woodland at Strangways, I was delighted to see a small red speck climb out of the thick moss.


Red Velvet Mite

The red speck was a Red Velvet Mite – an arachnid of the family Trobidiidae. Unlike other arachnids, their bodies are not segmented. They have two eyes but use chemoreceptors (smell but with no nose) and sense vibrations to find their prey – primarily other invertebrates.

Climbing over rough terrain

They will emerge from the soil after rain. At times I’ve seen a horde of these tiny animals, up to 50 at a time, ranging from less than 0.5mm to about 4 mm long, quickly dispersing. This one was on its own and was about 3mm long.

Apparently, male Red Velvet Mites will construct a little boudoir of plant material and spermatophores – little clumps of sperm – into which he will invite a prospective mate. He does this by waiting for a lady to pass and then does a little dance for her. If she likes what she sees, she sits on one of his spermatophores and impregnates herself.

Not far from where I found the little red cutie, I found a male midge sitting on a Golden Wattle bud. I’ve struggled to get a photo of the wonderful feathery antennae that the boy midges sport, so I was very pleased that this lad sat still long enough to get a decent shot.

The moths that ate Strangways – well not quite

Since the heavy rains of 2010-11, we’ve had quite a growth of Cassinia sifton at our place. In recent weeks, it has become favourite fodder for Looping Caterpillars of the moth genus Chlenias.

Chlenias caterpillar

Almost all of the Cassinia bushes at our place have at least a few of these munching away, ranging from 10-30 mm long. As there is a great abundance of the shrub in our bush, I’m very happy that someone is keeping it in check. There is some debate about whether Cassinia sifton is truly native to Victoria or whether it came from NSW during the early gold rushes. Until recently it was classed as one species with Cassinia arcuata which is now a rare species only found in the northwest of the state.

Chlenias caterpillars are also enjoying some Golden Wattle

I was trying to get some photos of a Shining Bronze-Cuckoo (Chrysococcyx lucidus) at our place the other day and found two on the ridge, chasing each other in an amorous sort of way. They got themselves deep into a Cassinia bush where one (a male I assume) offered the other a series of Chlenias caterpillars. Due to the dense bush I was only able to get a pretty ordinary shot of her eating her gift. The male was hidden behind some of the branches, but I figure this one definitely belongs in this post.

Also in great abundance in our bush at present are Fungus Gnats. As I prowl around the bush looking for subjects, I am struck by how important these tiny insects are for pollination and as fodder for other invertebrates. They are also very challenging to get good photos of.

This one seemed to be drinking from the gland at the bend of the leaf stem of a Golden Wattle. Mostly I see ants doing this.

Nocturnal ants are also common and very important during winter nights and again Golden Wattles are favourite haunts.

Camponotus on a Golden Wattle

Harvestmen are arachnids that look like spiders, having eight legs, but unlike spiders they only have two eyes (spiders have eight) and have external mouth parts that crunch their prey rather than sucking the insides out as spiders do. I’ve seen harvestment from time to time, but this year I’ve seen a lot of Opoliones harvestmen, usually on wattle and eucalypt leaves.
