Tachnid Flies are nightmares of the insect world.  The adult insect lay eggs on their hosts such as caterpillars and then the larvae hatch,
 burrow inside and feed on the host.  According to Bugguide.net, practically no insect is safe from their attack.  It is not hard to find
and identify this Gymnosoma tachnid fly in the outdoors because of its unique abdominal pattern.  The infamous Bot Fly, which
lays eggs on mammals, is of the same Super Family as tachnid flies. © Carol Davis, 6-22-2008
