Insects are really cool even as they are, but when they come in blue, they are just awesome. Blue is just cool. My favorite color too :). Here are some cool blue insects I have come across. Gotta love them! I also believe these cool insects are why most people take up slr macro photography! If you need more reasons to start liking and photographing insects, hear it from Sir David Attenborough in his ending speech in the fantastic DVD series: Life In The Undergrowth.. Invertebrates don't need us human. It's we that need them.
Most of the images were shot with a Canon 40D, Canon MPE65 1x - 5x macro lens, and MT24EX Twin Flash with DIY Diffuser.. Typical setting: 1/200, F11, ISO100, handheld.
An amazing blue and spiny soldier fly. I was really amazed and excited when I saw it last Saturday! I found it at the same forest where i found the blue robber fly. Hmm..think I'll be going back there to look for more "blue" bugs :D
Soldier fly, Clitellaria bilineata
Blue robber fly, subfamily Laphriinae. Might be an Orthogonis sp.
Slightly "blue" ant :)
Not sure if this counts as blue..
Another type of blue soldier fly, Cibotogaster sp. (male)
A blue tiger beetle
A somewhat blue damselfly
Lastly, a blue jumping spider
Signal fly, Platystomatidae, a species of Loxonevra near decora Fabricius.
Blue bee, Thyreus sp.
If these cool and exotic blue insects still can't convince you to take up slr macro photography, then I don't know what will :P
