We are currently investigating the mechanisms whereby the genetic differences between populations might have arisen and the role of selection in reinstating diversity subsequent to colonization of an island.
In collaboration with Dr. Jonathan Coddington (Smithsonian Institution) we are generating a phylogeny for the Theridiidae using morphological, behavioral, and molecular data.
The Theridiidae comprise a diverse array of genera, with representative taxa exhibiting a broad spectrum of behavioral, ecological, and morphological attributes.

insects, are spun by members of the Theridiidae and Pholcidae; but by common consent the so-called orbicular web, so characteristic of the Argyopidae but by no means confined to them, is regarded as manifesting the greatest 'perfection of instinct in snare-spinning.
If in the latter case the spider be afraid to come to close quarters, various devices for securing it are resorted to.
There is one possible exception, however, to the innocuous nature of the poison and this is supplied by the species of the genus Lathrodectus, one of the Theridiidae.

 Florida Entomologist, v. 82, n. 2, p. 359
Spiders of the genus Argyrodes Simon 1864 (family Theridiidae, cobweb spiders) live almost exclusively in the webs of other spiders.
Argyrodes species may interact with their hosts in several ways, as a kleptoparasite stealing the hostís prey, as a host predator, web-stealer or commensal (see Cangialosi 1997 for discussion).
In the course of behavioral studies on a Floridian endemic spider, the red widow Latrodectus bishopi Kaston 1938 (Theridiidae; Marion County, Ocala National Forest, along Hwy 40, 1/4 mile west of Central Lookout Tower) three different species of Argyrodes were collected from their hostsí webs.
