But first, I digress with a photo of a Grey Box (Eucalyptus microcarpa) blossom, just because they are beautiful and they are out. And in this image, a tiny pollinator can be seen poking out of a blossom. Another on one of the buds.

There seem to be more insects and other invertebrates out in recent weeks than for most of summer, but the numbers are still low it seems to me. Regulars like Eucalypt Tip-wilter Bugs ( Amorbus sp.) are about, but fewer than in most years. Both adults and nymphs can be found in our bush at Strangways. They make good subjects as they don’t seem to care about the proximity of the camera, possibly confident in their stinky defenses.The bugs use their sucking mouth parts to draw sap from Eucalypt leaves.

I think the little hole at the bottom of the body between the second and third pair of legs in the adult is the ostiole through which the stinky emission is delivered if needed.
The profile of the bug shows the ostiole.

Mirid bugs also suck sap from leaves. They are much more slender than the Coreid bugs like Amorbus. I found this one on a Long-leafed Box.

Up close, the feeding method is more obvious
I was pleased to get a quick shot of another botherer of the Grey Box, a Leafcutter bee (Megachilidae) These solitary bees live in the ground and line their nests with cuttings of leaves. There seem to be a lot of ground nesting bees checking out the soil surface at present, but they’ve decided not to stick around when the camera is near.
The little wonder that really blew my socks off one night recently was this strange little insect, all of 8mm long, crawling around the base of our lemon tree. I gently picked it up with a leaf to get a good view (and photo) before putting it back on the edged of the planter box where I’d found it.
Had me intrigued!
By trawling through various sites, I found a match on Insects of Tasmania – a very useful web site for identifying insects. It is a Feather-legged Assassin Bug (Ptilocnemus femoralis). Assassin Bugs prey on other insects, ambushing them and then poisoning them with their long mouth parts and injecting enzymes that dissolve the internal organs so the bug can suck the life out of their prey. Ptilocnemus is specialised to feed on ants, secreting a chemical which attracts and paralyses them before the life is sucked out of them. What a find!
