I harvested some bunching onion seeds, today, likely Crimson Forest. I took a brown paper bag, put the heads inside, and shook them to get the loose seeds to fall into the bag. When I finally looked in the bag, it had lots of earwigs in it! I hadn't seen any in the flowers, but I guess they hide in them!
The pictures here with the flower heads are before I shook the seeds (and earwigs) in the bag. So, you can see how nicely the earwigs are hiding. The huge leaves are from horseradish plants.
To remove all the earwigs, I had to dump the seeds (and some of the earwigs) out on a plate, let the earwigs crawl away, shake the remaining earwigs out of the bag, and pour the seeds back into the bag.
