Bears can be a problem for beekeepers because they frequently destroy domestic bee hives to eat the bees and honey found in the combs. Crop and Garden Pests Invertebrates cause millions of dollars worth of damage to crops each year. Every few years, populations of some species of grasshoppers increase dramatically and decimate local grain crops. Some caterpillars, beetles and slugs eat garden vegetables and reduce the harvest. Tent caterpillars prefer the leaves of poplar trees, but often attack ornamentals around houses and parks.

Some people enjoy collecting various insects and arranging them for display. Butterfly and beetle collections are perhaps the most common.
