Family Oedemeridae
- This page contains information and pictures about Lycid-mimicking Pollen Beetles
that we found in the Brisbane area, Queensland, Australia.
-
- Body length 15mm
-
- This beetle was first found near Bulimba Creek in Yugarapul Park on Acacia leaf
during early summer Nov 2007. This beetle look like a Lycid
Beetle but it is in family Oedemeridae. This beetle mimic the Lycid
Beetle to gain some protections. Details please check our mimicry
complex page.
-
 -
- This beetle may also be confused with the Tmesidera rufipennis in family
Meloidae or the Eroschema poweri in family Cerambycidae. Both of them
are in the Lycid mimicry
complex. The beetle can be distinguished from others that this genus Pseudolycus has the antennal segments 3-8 broad
and flattened.
-
- From reference information that Oedemerids are themselves
usually toxic, so the mimicry is of the Mullerian
type.
-
 -
- The beetle was also found in Botanic Garden. It was later winter Sep 2007,
Feeding pollen on Acacia flowers
