Sphinx and Hawk Moths (family Sphingidae)

Sphinx moths and hawkmoths beat their wings incredibly fast as the sip nectar from flowers, and as a result are sometimes mistaken for hummingbirds. They are some of the fastest flying insects, capable of flying nearly 12 miles/hour.

Tent Caterpillars and relatives (superfamily Lasiocampoidea)

Tent caterpillars are social insects that live within a large webbed “tent”, which helps them to regulate their temperature and stay warm enough to digest young leaves in cool weather. Only those of the Malacosoma genus build tents.
