|Blacktailed red sheetweaver|
O. Pickard-Cambridge, 1896
The black-tailed red sheetweaver, scientific name Florinda coccinea, is a species of web-building spider belonging to the family Linyphiidae. It is the only species in the genus Florinda. It is sometimes known as the red grass spider. This species is common in the southeastern United States, inhabiting grasslands, lawns, and agricultural fields 
F. coccinea individuals are bright red in color, with a black caudal tubercle. Typical body length is 3–4 mm for adults, with females being slightly larger than males.
Webs spun by F. coccinea consist of a horizontal sheet of non-sticky silk, with a tangle of stopping threads above. The stopping threads intercept flying prey and cause them to fall into the sheet below, where they are attacked by the spider.
