Why are ladybugs considered a "beneficial" insect? Ladybugs feed on aphids and other soft bodied insects that feed on plants. The ladybug feeds on these pests as the adult ladybug and as the larva. One ladybug can eat as many as 50 aphids a day.
You don’t usually hear about insects being endangered since they’re typically found in huge numbers. However, the Rainbow Leaf Beetle (Chrysolina cerealis) is an extremely rare species of bug that is only found in a few small populations.
I took this photo at the Montreal Insectarium, and the whole reason for liking this beetle was the parts near the eyes that look like mega thick eye-lashes. Not many people would find a beetle pretty, but I think this one just looks so flirtatious!
