I was listening to an episode of The Infinite Monkey Cage that was discussing wasps versus bees. As part of the conversation, one of the contributors mentioned that wasps like sweet things early in the season when they are feeding their young but, later in the year, they are only feeding themselves and they want protein (or the other way around if I have remembered incorrectly). I didn’t know anything about this before but then, shortly afterwards, we were sitting out on the deck after dinner and a wasp landed on a plate and then flew off with a chunk of chicken. This chunk was almost as big as it was.
A week later, we were back out on the deck and, with dinner done, a wasp came back to check out the leftovers. This time I was ready with my phone. Sure enough, it landed on my plate, checked out a piece of corn and then homed in on some chicken. A few bites later, it had extracted its meal and got airborne and away. I had my video proof, so I was happy. It came back for a second piece a little while later, so I guess it was storing food for later.
