Diptera


I didn’t know there were craneflies this pretty! It was quite a surprise to see it sitting on a tree.

Well, our long mosquito season is well and truly here. They were out in force today…

I’ve never noticed this kind of robber fly before, probably because it resembles a bumblebee. It has wonderful eyes that follow your every move. A pretty efficient predator I’d say.

I managed to get bitten by a couple of mosquitoes today, and was proud to capture a photo of the first one without killing it. How kind! I’m sure that the novelty of being bitten will wear off soon and I’ll be back to swatting at them as soon as I spot them!

Bibionid flies (ke-bae) have many common names in the USA, the most common being “march flies” or “love bugs” (although these are different species to the one below). The larvae are in huge numbers in the soil/leaf-litter of the forest floor and are very important for decomposition and the recycling of nutrients.

It was getting dark when I took these photos, so they are pretty poor quality.

This is the second time I’ve found one of these huge craneflies (Mikado gaganbo), but the last time I couldn’t get decent photos. I actually trod on this one by accident and it suffered no harm, so they seem to be pretty tough creatures! As you can see from the photo of me holding it, this really is a big insect, with a wingspan of around 8cm and a legspan of 15cm. Harmless of course, but I’m sure it would scare many people! [In comparison, the craneflies common in the UK are around 5 or 6cm from legtip to legtip.]
