World Checklist of Extant Mecoptera Species
WORLD CHECKLIST OF EXTANT MECOPTERA SPECIES
Earwig-flies are so-called because adult males have greatly enlarged
genital claspers that superficially resemble the heavily sclerotized
cerci of earwigs. Adults of the North American species are found in
mid-summer, usually in forests near streams or moist seeps. Most individuals
have been collected using flight intercept traps. The Australian species
has been collected most frequently using pitfall traps in drier, more
open savannah or desert. Nothing is known of immature stages.
The two known species have a remarkable geographical distribution.
One species is only found in southwestern Australia. The other species
is found in eastern North America. Until 80 years ago, all North American
specimens were known from along the East Coast. However, during the
last few decades they have been collected progressively farther west,
and now are known as far west as Missouri and Kansas. Byers has speculated
that this apparent range extension may be due to increased use of flight
intercept traps, which are now a primary collecting device for these
creatures. Byers has also postulated that Meropeidae may previously
have had a Gondwanian distribution and have moved into North America
from South America, where the family has either gone extinct or remains
to be discovered.
