Wild About Insects - Illinois Katydids!

Family and Species Gallery

Kingdom: Animalia - Animals are multicellular organisms that rely on other organisms for nourishment. Their cells do not have cell walls. Most animals are capable of movement at least in some portion of their life cycle. Reproduction is generally sexual, but in some animals asexual reproduction may be utilized at certain times.
Phylum: Arthropoda - Arthropods have an external skeleton, a segmented body and jointed appendages. They are covered with a cuticle made of chitin. The cuticle is hard and must be molted, or shed, for the animal to be able to grow. Compound and simple eyes are present. They have an open circulatory system. There are nearly 28,000 types of arthropods known from Illinois. They are represented in all Illinois habitats.
Class: Insecta - Insects have three body divisions, the head, thorax and abdomen. They usually have three pairs of legs and two pairs of wings. Legs and wings are positioned on the thorax. Most insects have one pair of antennae. A few insect species have no antennae.
Order: Orthoptera - Most of these insects have four wings, although some are without wings. The body is long and thin. Mouthparts are for chewing. These insects undergo simple metamorphosis (egg, nymph, adult).
