Cover Illustration: A worker (top) and queen (bottom) of Pseudomyrmex pallidus twig ants. The queen has scar tissue from where her wings were attached. These ants are known for their elongate bodies and large eyes, likely adaptations to their arboreal habitat. These were collected living in the hollowed shoots of dead Smilax sp. in the Apalachicola National Forest near Tallahassee, Florida. (Image courtesy of Adrian A. Smith.)
