Bugs or Insects?

by Skip Via

What’s the difference between a bug and an insect?

All bugs are insects, but not all insects are bugs. Insects typically have a body segmented into three parts (head, thorax, and abdomen), a hard exoskeleton, six legs, and two antennae. Bees are insects. So are dragonflies, ants, butterflies, beetles, moths, and crickets among many others.

But there is one animal in this story that is not an insect. Spiders usually have only two body parts, basically a combined head and thorax called the cephalothorax and an abdomen. They don’t have antennae, they have mouths that are designed for piercing their prey, and they are related to ticks and scorpions.

Speaking of bees, Montana has the greatest variety of native bumblebee species of any state–at least 28. There are also honeybees, carpenter bees, mason bees, leaf cutter bees, and several others.

Crab spider meets bumblebee. Judging from the absence of the bee’s head, it looks like the crab spider won this round. (Interesting fact–crab spiders walk sideways, like crabs.)
