Common Potter Wasp
A North American potter wasp that builds small globular mud cells on plant stems and twigs. The female suspends her egg on a silk thread inside the pot before sealing it.

The egg is hung on a thread from the ceiling of the pot so the larva can begin eating the paralyzed caterpillars below without being crushed.

A small seed bug native to southern Europe that has become an invasive nuisance pest in the northwestern United States. It aggregates in enormous numbers on and inside buildings in summer and fall.
Did You Know?
Thousands can invade a single home seeking shelter, producing a foul odor when disturbed or crushed.
