As everyone knows, Tiger Beetles are pretty much the most beautiful and awesome predators in the world (ok, maybe not everyone knows, but they should all agree). I discussed them a little here, but I had only experienced them in the states, never before in South America. My first night in Pacora I found a few under lights at the soccer stadium here. Naturally I collected them for pictures.
Since then, I have encountered the species very commonly on sidewalks and dirt roads after dark. Never before have I encountered a night tiger beetle, though I have read of their existance. These guys are cool as they don’t fly much - they are really unhappy to, though you can make them – so you can just grab them from the ground (if you don’t mind a little pinch).
They really vary in color from metallic emerald green (like C. sexguttata in New England) to a beautiful deep purple, which seems to be the more common color. I have not encountered any larval holes yet, though I would love to raise these larvae – tiger beetle larvae are really interesting as well.
I think it is in the tribe Megacephalini... but I don't have any references here, so take that one with a grain of salt.
