Scarce Stag Beetle
A small metallic blue-black stag beetle with modest mandibles. It develops in red-rotten beech wood.
Did You Know?
Despite being called scarce it is actually fairly common but overlooked due to its small size and dark coloring.
Flattened Giant Millipede Beetle
A large, flattened bess beetle with a shiny black body and a small horn on the head. Adults and larvae live together in rotting logs in a subsocial arrangement. Adults produce sounds by rubbing their hindwings against the abdomen.
Did You Know?
Parents feed their larvae pre-chewed wood and communicate with them using stridulatory sounds, one of the few examples of parental care in beetles.
