Sandy Skvoy, age 11, of Huntsville, Ala., for her question:

HOW DO MOTHS DIFFER FROM SKIPPERS?

Usually it is no big problem to tell the moths from the butterflies. The butterflies have slender bodies and skinny antennas tipped with bumps. They fly by day and rest with their velvety wings held upright over their backs. The fatter, furrier moths have wide, fuzzy antennas. They tend to fly by night and rest with their wings spread flat. Most butterflies spend their pupa stage in chrysalises and most moths in silken cocoons.

The frisky little skippers are classified as butterflies, though even the experts are not sure. Like the moths, they have fat furry bodies and big furry heads. They also spin silken cocoons and rest with wings at their sides. Unlike the moths, the skippers fly by day and have thin, knobby antennas. Most experts suspect that these in betweens resemble the ancestors of both moths and butterflies.
