Hi Bugman,
I hope you can help explain what’s going on in this picture. I was on top of the mountain taking sunset photos when luckily I looked down and saw what looked like a giant wasp dragging a trantula. The wasp was walking backward. Both insects were very much alive. I thought I read that their is some flying insect that captures live prey and then pulls it underground to lay eggs on it and the young feed off the paralyzed captive. I followed this pair until they disappeared into the long grass. Could you please tell me if that is indeed a wasp and what it plans for the spider? I live in Costa Rica. Thanks,
Jordan

hi Jordan,
The information you have heard is basically correct. Tarantula Hawks are large wasps in the genus Pepsis found in the Americas. The female wasp stings and parazyzes a Tarantula and drags it into a burrow where she lays an egg. The young wasp larva hatches and has a fresh food supply, eating the Tarantula alive. Thanks for the awesome photo.
