Description
"The black caudal tubercle is the key. Once you see a bright orange spider in a horizontal web with this feature, it is almost always Florinda coccinea. Ceraticelus or other orange Erigonids don't have this black caudal tubercle" (Marc Milne/BugGuide).

The blacktailed red sheetweaver (Florinda coccinea), also known as red grass spider, is a species of dwarf spider. It is the only species in the monotypic genus Florinda. It was first described by Octavius Pickard-Cambridge in 1896,[3] and has only been found in Mexico, the West Indies, and the United States.[1] It is common in the southeastern United States, inhabiting grasslands, lawns, and agricultural fields.[4]
Description
[edit]
F. coccinea are bright red in color, with a black caudal tubercle.[5] Adults typically grow to 3 to 4 millimetres (0.12 to 0.16 in) 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.
