When I encountered the planthopper above, I had no idea what was going on. While not entirely sure, I assumed that might be a parasite on its abdomen. I had wanted to get a closeup of just the parasite, but when I went to grab the planthopper, it jumped and flew away with little difficulty. The parasite must not have been as much of a hindrance as it would appear.

Here’s a crop of the image above showing the parasite.

It didn’t take much searching on the internet to determine that this must be the larva of a wasp in the family Dryinidae. There are plenty of images of larvae on BugGuide. According to Wikipedia, a larva initially feeds internally on the host. Only later in its development does it protrude the host as shown here.

I feel lucky to have seen this. As is usually the case, this just whets my appetite for more. Now I’ll be on the lookout for the odd looking adult.
