One of my biggest inspiration when it comes to super realistic display flies back in the days (and still) was Graham Owen. I’ve mentioned Graham previously here and he is worth mentioning again. Anyway, a few years back I sent him some ants and a beetle that I did that I had (quite badly I must admit) clipped of the hooks from to make them useful as just insect imitations.
Anyway, he ended up taking some great photos of them fighting over some sugar which he used on his website later that year. I still kept those photos because I find them really, really cool.
