This is an attractive little bug and very useful to humans as well. Ladybugs are important predators because they feed on aphids which in turn eat crops and plants in large numbers sometimes causing serious damage. Ladybugs are easy to find in a park. The praying mantis is an exquisite predator perfectly evolved for hunting. The mantis will eat any number of insect pests so they are a welcome sight in our provincial parks.
Flesh flies are a common sight in provincial parks.
They like to feed on sweet stuff like nectar or sap that is flowing from tree wounds. The adult female lays her larvae within rotting flesh or within other insects or animals. The larvae then feed on the living host until they mature. I know it looks like a caterpillar not a moth. This is actually the caterpillar stage of the Gypsy Moth which is a huge pest not only within Ontario's parks but in forests throughout Ontario.
