Digger Wasp with Katydid On Biolab Rd at Merritt Island yesterday, I saw a Digger Wasp carrying a Katydid. It landed on a branch, I guess to rest for a little bit, and this allowed me to take a few photos. I'm no expert on insects, but according to the good folks at bugguide.net, the Digger Wasp is Sphex jamaicensis (no common name) and the katydid is an Agile Meadow Katydid. Female Digger Wasps look for Katydids and Grasshoppers, sting them to paralyze them, and then bring them back to one of their tunnels. These photos illustrate how. They grasp the antennae of their prey in their mandibles and then wrap their legs around the body of the insect. This one is quite a bit larger than the wasp, which is perhaps the reason why it rested and posed for photos. Once bringing her prey into her tunnel, she will lay her eggs there and then close up the tunnel. When her eggs hatch, the larvae will eat the Katydid. Sorry if that's gros...
