commonly as the Cobweb Beetle, the larva of Ctesias
serra lives in crevices and under the bark of
ancient trees, feeding on the left-over meals of spiders.
The hairs are part of it's defence mechanism against
attack by spiders - thrusting them forward when
threatened. The adult beetle is dark brown in colour and
rarely seen it seems in its natural habitat, so this
beetle is more commonly recorded as a larva. Included
here, are six photographs showing the pupation and adult
emergence. The whole process took eight days to complete.
