This large Assassin Bug (Family Reduviidae) is grooming its antenna and has to rear its head up and backwards (thus showing us its beak) so that the long antenna can be completely drawn between the front legs. I found this insect in Costa Rica on a lighted "bug sheet" at night and photographed it in my portable light tent setup. 5D II, 100 mm macro, 1/200, f/16, ISO 100, MT24-EX (fired downward through the light tent), hand held. There are a few jagged edges due to the low resolution of this image. All comments are welcome and appreciated.
Another winner, Steve! You couldn't have asked for a better pose.....not only some action but it's also displaying that menacing beak! Your portable setup comes through again.
