The recently discovered Sirenobethylus charybdis has features not seen in any known insect living today, researchers say.

However, the hind wings aren’t its only striking features. S. charybdis appears to have evolved a unique, three-flapped abdominal setup similar to the leaves of a Venus flytrap. The paddle-like lower flap is particularly distinctive due to its hair-like bristles.

Bizarre parasitic wasps preserved in amber about 99 million years ago had trap-like abdomens that they may have used to immobilise other insects
