Blacktailed red sheetweaver

Florinda, commonly called black-tailed red sheetweaver or red grass spider, is a monotypic genus of dwarf spiders containing the single species, Florinda coccinea. It was first described by Octavius Pickard-Cambridge in 1896, and has only been found in Mexico, the West Indies, and the United States. It is common in the southeastern United States, inhabiting grasslands, lawns, and agricultural fields.
Description.
"F. coccinea" are bright red in color, with a black caudal tubercle. Adults typically grow to long, with females growing slightly larger than males. They have two rows of eyes; two on the top row and six procurved on the bottom.
Webs spun by "F. coccinea" consist of a horizontal sheet of non-sticky silk, and 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.
