I keep insects as pets, and this seems to be a common way to get live insects from point A to point B. I felt a little bad about having them go through the surely-unpleasant process of being in the mail for a couple days, but they came out on the other side healthy enough that I didn't lose any.

Makes the idea of keeping pet insects that no store or breeder sells near you a lot more affordable, which is nice, since a lot of insects make such easy and practical pets.
