Unit II Kansas Arthropods Information

Introduction to Arthropods

• Insects and spiders belong to a larger Phylum
  Arthropoda, which means jointed leg.
• Insects are characterized by having 6 legs with
  joints, and 3 body parts head, thorax and
  abdomen. Most have either one or two sets of
  wings.
• Most insects go through various life stages,
  where they change in form and appearance. There
  are many variations, but these changes are called
  metamorphosis.
• Very few insects are harmful to humans or crops.
• Many insects are very beneficial, especially the
  ones that pollinate plants.

3
Arthropods, cont.

• Spiders are characterized by having 8 legs and 8
  eyes. They have two body parts cephalothorax
  and abdomen.
• Identification of most insects is very difficult.
  Some of the more showy insects, like most of the
  ones in this unit, are easy to learn the species.
  Learning which Order insects belong in is the
  first step to being able to find the species in
  field guides.

Monarch

• Order Lepidoptera, the moths and butterflies
• Only migratory butterfly that has a migration
  similar to birds.
• When they breed, they lay eggs on milkweed
  plants, and the breeding adults live for about
  one month.
• About 4 generations are hatched in a summer, and
  the ones that hatch out in August and September
  are the ones that will fly to Mexico for the
  winter, and there they will congregate by the
  millions, and live for about 8 months. They are
  not in a breeding state.
• As they fly back north, they breed and die. The
  next generations continues going farther north,
  breeding and dying, until the end of the summer
  and the migratory cycle continues.
• Monarch Watch tags the monarchs with special
  stickers and records the data to keep track of
  migration. See www.monarchwatch.org for more
  information.

Monarch cont.

• Monarch butterflies are poisonous (not
  venomousyou have to eat them to get sick).
• Their black and orange colors are a warning to
  would-be predators that they are poisonous. If a
  bird eats one, it gets sick and throws it up, its
  heart beats very fast and it remembers those
  colors and does not eat it again.
• Monarch caterpillars live on the milkweed plants,
  which have a cardiac glycoside in the milk that
  is poisonous to most animals. The caterpillars
  can eat it and not get sick, and that is what
  makes them poisonous to other predators.

Monarch does not have this straight line.

Viceroy

• Order Lepidoptera, the moths and butterflies
• NOT poisonous, but it mimics the monarch
  butterfly, which provides it protection from

  ½ inches long.

  lay eggs in the twigs. When the eggs hatch, the
  nymphs fall to the ground and develop in the
  soil. They feed on the roots of the host plant.

  empty skins are common sights for most people.
