Cretaceous Burmite: Evidence for a Remarkable Predator Prey Relationship

[Biotalker]

An unusual type of beetle called Cascomastigus monstrabilis, of the subfamily Scydmaeninae or ant-like stone beetles, has a remarkable adaptation of their antennae. The eyelash looking structures called setae give the antennae the ability to serve as a trap to catch their prey, the tiny and numerous Collembola or springtails. The clublike maxilla palps may help to bring them to the beetles jaws.

Predator: Here are three Cascomastigus monstrabilis from my collection. They range from 6-9mm long.

Prey: Collembola or springtails. They are often found in burmite in very large numbers and this piece of amber is no exception. I can’t imagine counting them all on this piece. They are approximately 0.5mm in length.
