Sometimes when you are under Disaster Emergency Self-imposed I-refuse-to-get-coronavirus Quarantine, you get bored. I was wandering around the yard one day and got down on my knees to look at crane fly larvae. While I was there, I noticed these crazy lace balloons attached to the stems of Bur Clover (Medicago polymorpha).

It only took a second to spot the larvae, too.

I was fascinated watching the little larvae wiggle around in their lace balloons, but I couldn't tell if they were related to the egg stage or the cocoon stage. So I sent my field assistant (read: nephew) to bring my phone camera and collection supplies. I was able to open one of the lace balloons to see that it was a cocoon with a pupa inside.

But what ARE THEY? I suspected they were some kind of beetle (probably weevil based on the "snout" of the pupa,) but there were several species in the grass that day, so I collected a few cocoons to see what emerged.

And here it is... the Alfalfa Weevil.

I didn't know at the time to look for eggs in the stems or I would have had the full life cycle. Nevertheless, it was hands-on nature learning at it's finest.
