The mission blue
butterfly flits and flutters, looking for just the right flower in
which to lay its eggs. In a few weeks, these eggs hatch into caterpillars.
Sometimes, these caterpillars are guarded by ants that protect them
from enemies, like flies and other insects. The caterpillars "pay"
the ants back by giving off a sweet, gooey liquid that the ants like
to eat.
