When spongy moths have an "outbreak," the caterpillars defoliate trees (eat all the leaves).
Insects are invertebrates. Their bodies are clearly divided into a head, a thorax, and abdomen. They also have three pairs of jointed legs and usually two pairs of wings.
Watching butterflies is a fun summer activity and you can invite them to your very own yard.
Butterflies go through a complete metamorphosis. This means they have four stages to their life cycle: egg, larva, pupa, and adult.
