Blue-eyed Ensign Wasp

I see these wasps quite often, flitting about, with the little black abdominal part on the stalk vibrating noticeably. However, it wasn’t until recently that I identified them.

This is a Blue-eyed Ensign Wasp (Evania appendigaster) and it’s considered a beneficial insect because it’s a parasitoid, which lays it’s eggs in the eggs of cockroaches. The wasp’s offspring feed off the cockroach eggs, which results in a few less cockroaches in the neighborhood.

Alas, we do not appear to be running out of cockroaches, or seem likely to do so in the immediate future.

Seriously subdued spider in seven shocking scenes

At work recently, I was alerted to the presence of an odd wasp, with a ‘sac’ under its body, trying to get into a small hole in the window frame. I grabbed my camera, opened the window, and took photos.

It quickly became clear that the ‘sac’ was a spider, and not a tiny one either. What was less clear was whether the wasp would succeed in its quest. I assume the hole is a drainage outlet, but what the wasp was up to was less clear. A little research cleared that up.

The wasp is a Yellow-legged Mud-dauber Wasp (Sceliphron caementarium). Not sure what kind of spider it is, but I do know its days are numbered. Sadly for the spider, it will not be a swift end. According to Wikipedia, “After building a cell of the nest, the female wasp captures several spiders. The captured prey are stung and paralyzed before being placed in the nest (usually 6-15 per cell), and then a single egg is deposited on the prey within each cell. The wasp then seals the cell with a thick mud plug. After finishing a series of cells, she leaves and does not return.” Notice that the spider is paralyzed, not dead. Got to have fresh food for the kids!

The bugs in the next gallery were all on the same Monstera leaf, which had accumulated falling flowers from a palm tree.

The Numbers Game #24
