- This page contains information and pictures about Darkling Beetles
in Subfamily Tenebrioninae that we found in the Brisbane area, Queensland, Australia.
Tribe Amarygmini - True Darkling
Beetles
- Beetles in this tribe are dark colours with metallic reflections. There
are nine striae on elytra (longitudinal lines on wing-cover).
-
- Chalcopterus Beetle I
- Chalcopteroides sp., Amarygmini, body length 20mm
- This beetle is black in colour. It is shiny in metallic green or red depend
on the angle you look at it. We took this picture in a forest near Wivenhoe
Lake in late summer 2002. The beetle was resting on a gum tree trunk. Here we like
to thank Mr. Justin Bartlett in Brisbane. Justin sent us email to identify this
beetle. Justin also advised that there are many similar looking species in this
genus that are commonly found on, and under bark of Eucalyptus. They are all
black with an iridescent sheen.
