Common Insect Species of Northwestern Ontario





Class Insecta (Hexapoda) Subclass Pterygota
- insects with wings, or insects whose ancestors had wings

Order Lepidoptera
Butterflies, moths

Monarch Lepidoptera is one of the largest order of insects, with over 100,000 species worldwide. Lepidopteran larvae have chewing mouth parts with strong mandibles. Most adults have long, coiled, tube-like or straw-like mouthparts which are used for sucking up plant nectar. All Lepidoptera undergo a complete form of development (egg, larva, pupa, adult). Many butterflies and moths are enjoyed and collected because of their colourful beauty. They normally have rather hairy bodies, long antennae and their wings are covered with tiny scales. These scales reflect the bright colour patterns of the wings, and form eyespots in many moths. The larvae, which are called caterpillars, eat plants and often cause considerable damage to forests, gardens, and croplands are the forest tent caterpillar, Malacosome disstria and thegypsy moth Lymantria dispar. Common species in northwestern Ontario are the monarch (Danaus plexippus), mourning cloak (Nymphalis antiopa), and luna moth (Actias luna). The bright eyespots of the luna moth's hind wings frighten predators such as birds who might otherwise feed on the moth.
