Bowl and Doily spiders - Frontinella sp.

Around our house and especially near our outdoor lights in shrubbery are dozens of bowl and doily spiders.  They are small, their bodies were a little over an eighth of an inch long. They are easily seen on morning walks on our farm in taller grasses and weeds away from wooded areas when there is dew present.


The webs seemingly is not as organized as other spiders until closer inspection.  The total size of the webbing is about six inches in diameter.  There is a highly organized sheet (see below) of webbing at the bottom of the web that looks like a screen in a door (the doily).  Then an inverted cup or bowl section above this sheet.  It is all suspended by a random support system of webbing.

"The bowl and doily spider, Frontinella communis, is a species of sheet weaver found in North and Central America. It is a small spider, about 4 mm (0.2 inch) long, that weaves a fairly complex sheet web system consisting of an inverted dome shaped web, or "bowl", suspended above a horizontal sheet web, or "doily", hence its common name. The spider hangs from the underside of the "bowl", and bites through the web small flies, gnats and other small insects that fall down into the non-sticky webbing. The webs are commonly seen in weedy fields and in shrubs, and may often contain both a male and a female spider in late summer - like many linyphiids, Frontinella may cohabitate for some time."
