Bug #1 -- Centipede

Kingdom: Animalia
Phylum: Arthropoda
Class: Chilopoda
Order: Lithobiomorpha
Family: Henicópidae

Centipedes are flat, wormlike creatures with fifteen or more pairs of legs (appendages). One pair for each body segment. The antennae on a centipede has at least fourteen or more segments. The first set of appendages behind the head are clawlike, and are called poison jaws. These jaws are used to trap and paralyze their prey. Eyes may be present or absent: if present. they usually consist of numerous ocelli. Centipedes can easily be found in soil, under bark, rotting wood, and other debris. They are very active, fast-running animals, and are very predaceous: they feed on insects, spiders, and other small animals. Small centipedes are harmless to man, but the larger ones can give quite painful bites. American centipedes can range in size from a few millimeters to just over six inches in length. Their color varies in species from pale yellow to dark brown. Two families make up the order Lithobiomorpha. The difference between the two families can be determined by using and comparing the eye structures of each.

Bug #2 --Small Milkweed Bug

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Hemiptera
Family: Lygaeidae

The Order Hemiptera are the "true bugs". The mouth parts are of the piercing-sucking type and are in the form of a slender segmented beak that arises from the front part of the head and usually extends back along the ventral side of the body. The Family Lygaiedae, or seed bugs, is a relatively large family of bugs. They are commonly found on vegetation and mostly feed on seeds. Color varies considerably, with the majority brownish, though some are brightly patterned such as the Milkweed Bug. It feeds on milkweed seeds. The chinch bug is probably the most injurious bug in this family. They attack wheat, rye, oats, barley, and corn. These bugs migrate on foot, and if they are abundant, they can destroy whole fields of grain. Many Hemiptera have scent glands and give off a characteristic odor when disturbed. This may be often unpleaseant to man.

Bug #3 --Ladybug or Ladybird Beetle

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Coleoptera
Family: Coccinellidae

The Ladybug is actually a ladybird beetle. These common beetles have a very distinctive oval shape and bright coloring. The head is partly or completely concealed by its pronotum or top shell. Both adults and larva of most species are predaceous. Feeding chiefly on aphids, but also seeking out scale insects, mites and other injurous forms in insects. Ladybird beetles are often quite numerous where these pests occur. They may eat up to 1000 aphids a day. Some species have been used commercially to combat scale insects injurious to the citrus orchards of California. Adults frequently overwinter in large groups under leaves or in debris. There are only two species of ladybird beetles that are phytophagous, which means feeding on plants. These can be serious garden pests.
