Diptera


This very large hoverfly looks and behaves remarkably like a wasp. It’s one of the biggest hoverflies at 20mm in length.

Japanese: shirosuji-naga-hanaabu
Scientific: Milesia undulata
Found at Yokoyama Village in Munakata (Fukuoka, Japan)

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

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.
