\\\”……Phorid flies are small; they are
about 1/8\\\” long. They are most commonly mistaken
for fruit flies. Although their body is similar
in color, phorid flies have a distinctive hump
in their thorax which starts behind their head.
They also lack the red eyes which fruit flies
have. The other key to identifying phorid flies
is how they move when you swat at them. Unlike
other flies which will fly away, the first move
a phorid fly will make is to run along surfaces
away from you. This unique characteristic alone
can be enough to identify them. Phorid flies
take a longer time to develop than fruit flies.
Although they can complete all stages in two
weeks, it usually takes more than a month for
them to go from egg to adult. Phorid flies
need moisture to develop. They like to nest in
drains, around leaky pipes and in the moisture
which is formed around condensers of refrigeration
units. I have seen several times where they have
established themselves under a slab because a
pipe had broken and was leaking water. Phorid
flies need anything organic to survive, and
meat or garbage foodstuff is more than enough
to allow them to prosper………..\\\”

…….They also \”squish\” into a dust-poof when you kill them…….
