(Cupedidae) imitates a bird dropping on a
Madagascan rainforest leaf. This mimicry
is interesting, since cupedids are a much
older lineage than birds!
Micromalthidae and are much larger, but they
resemble no other group of beetles. Four species of
Cupedidae, reticulated beetles, can be quite easily
found in North America. In western USA, males of
Priacma serrata are known to be attracted in numbers
to some brands of laundry bleach, which apparently
other continents with trade. Adults are
hardly ever seen, as the larvae are able
to reproduce without them. As beetle
taxonomy is mainly based on adults, the
species was considered rare. This suggests
that other species of Micromalthidae may
well exist undiscovered in less populated
parts of the world, since tiny larvae in wood
do not always attract attention. For this
reason, DNA examination of timber may
reveal new, unknown Micromalthidae
smells like the pheromone produced by the female.
In Asia, Africa, Australia, and South America, only
a few species of Cupedidae are known, and in
Australia and South America, some Ommatidae,
but none are ever common, and finding them is
usually a matter of great persistence or good luck.

probably the most primitive-looking living
member of this ancient lineage of beetles.

Beetle, among larvae. Strangely, it is the larvae that
will reproduce; the adult is not capable.
