Magnified 372X, approximately eight times greater than PHIL 9939, this scanning electron micrograph (SEM) revealed morphologic details found at the distal tip of this adult 'figeater' beetle's, Cotinis mutabilis, antenna. Known as a 'lamellate' type of antennae, the distal three sensorial segments have been folded over one another, which can be seen here in this image. This morphology is typically found in members of the family Scarabaeidae.The antennae provide the insect with data indicative of changes encountered in its environment such as chemical, thermal, and tactile queues.
