Diet of elusive red widow spider revealed by MU biologist
Date:3/20/2014

which often are larger and stronger than the spiders themselves, fly just above the tops of scrub vegetation," said Mark Deyrup, senior research biologist for the Archbold Biological Station, who co-authored the study. "Sometimes beetles hit the web strands between tips of palmetto fronds and tumble into the denser tangle of threads below, catching them in the red widows' webs."

Carrel has monitored red widow spider populations at the Station since 1987, but has found enough webs to study red widows' dietary habits only twice. During both time periods, Carrel worked alongside Deyrup to collect and identify prey from spiders' webs.

Carrel's study, entitled "Red widow spiders prey extensively on scarab beetles endemic in Florida scrub," appeared in the March issue of the Florida Entomologist. Funding for the study came in part from a grant from the University of Missouri in Columbia, MO.
