Yesterday, when I was walking my dog, I found a small abandoned-looking Mud Dauber nest. I occasionally crack open abandoned mud dauber nests to look for small founding colonies of Cardiocondyla, so I decided to crack that one open. When I did, to my surprise, a few caterpillars tumbled out. Upon closer inspection, there was a tiny little wasp larva sitting atop one of the caterpillars. I took him/her along with her food home and placed her in a test tube (I couldn't just let the larva die!). He/she is eating one of the caterpillars as I type. Has anyone ever raised one of these?
Also, the gender of this little guy can't be determined at the moment. Solitary wasps don't have female workers, so there is also a high chance of getting a male mud dauber.
-Note: Mud Daubers are wasps
