Bug With Bifocals Baffles Biologists

Cincinnati researchers are reporting on the discovery of a bug with bifocals.

"To the best of our knowledge, this is the first demonstration of truly bifocal lenses in the extant animal kingdom," the researchers state in the August 24 cover feature of the life-science journal Current Biology.

The new article is an exploration of two eyes of the larvae of the sunburst diving beetle (Thermonectus marmoratus). The two eyes have the bifocal lens, which the researchers have found in four of the larvae's 12 eyes, says researcher Elke K. Buschbeck, a UC associate professor of biology.

The article explains that using two retinas and two distinct focal planes that are substantially separated, the larvae can more efficiently use these bifocals.
