I’ve seen quite a few elongated beetles with rust/orange wing covers of late and assumed that they are Long-nosed Lycid Beetles (Porrostoma rhipidius) that I’ve photographed previously, but as I’ve seen them mostly on the wing, I’ve not been able to tell for sure. The first time I got a good look at my supposed Lycid Beetle through the macro lens, I was surprised to find it was actually a Red Belid Weevil – Rhinotia haemoptera. I’ve seen a great abundance of Belid Weevils this spring – more than I’ve ever seen, but none with these fantastic brick-red wing covers.
I was so stunned by its likeness to the Lycid Beetle. Then I found one of the the latter resting on a Cassinia.
Not just the red wing covers, but the black head and body are so strikingly similar. So I was intrigued to read on the very helpful brisbaneinsects.com that the Red Belid Weevil gets a considerable advantage by looking so like its Coleoptera cousin. It turns out that the Lycid Beetle is quite poisonous to eat and its bright colour signifies this to predators. The Weevil gets the same protection without having to be poisonous – just by looking like someone who is. It might also explain why both of these insects seemed utterly unconcerned by my interest, not for a moment considering themselves to be a meal.
Coleoptera means sheathed wing and is the name for the order of beetles. The covers that protect their delicate wings are called elytra. These are modified forewings that allow beetles to get into places that would otherwise destroy their delicate flight wings. Many beetles favourite escape mechanism is to simply drop before flying off, presumably as it’s faster than deploying wings from under the elytra. Often,however, they are quite happy to pose for photographers, like this Comb-clawed Darkling Beetle.
With the abundance of Shiny Everlasting blossoms happening at the moment, it’s a great time to get photos of flies as they collect pollen.
Flies are often nervous, but I find that when an insect has found a flower that it really likes, it stays put even with a camera and big flash diffuser right over it. Is it that it’s so good that it’s worth the risk, or do they not identify me as a threat?
Sleeping flies are also a bonus for the photographer. One seemed to be asleep in broad daylight on a Golden Wattle leaf. I’ve not been able to identify this one, but wonder if it might be a Tachinid fly.
A Hardenbergia in our yard is a favourite napping spot by night for Lauxaniid flies. I can guarantee finding quite a number of them most spring nights. They are always on the northern side of the plant. It took me a while to come up with the hypothesis that they liked the shelter from the cool southerly breeze that’s present however subtle on most nights.
