*Complete/Incomplete Metamorphosis:
Metamorphosis is called complete when there is no suggestion of the adult form in the larval stage, e.g., in the transformation from tadpole to frog or from larva to pupa to adult in bees and butterflies.
When the successive larval stages resemble the adult (as in the grasshopper and the lobster), metamorphosis is called incomplete.

Millipedes Found in North American woodlands as well as
deserts Long segmented trunk Round head with antennae pair for feeling,
smell, and taste Two pairs of legs attached to most segments Vary in color—black, brown, some are vividly
colored Avoid light—some are blind Play dead when distrubed Defense mechanism—stink glands May live for several years
