Basilica Orbweaver

Mecynogea lemniscata

Arachnid

A small, colorful orb-weaving spider that builds a distinctive dome-shaped web among shrubs and low vegetation.

The Basilica Orbweaver is a small native orb-weaving spider found from the southeastern United States through the tropics. Its common name comes from the dome-like center of its web.

It lives in shrubs, woodland edges, gardens, and other vegetation where flying insects are plentiful. The spider is often noticed beneath its web or beside a chain of egg sacs.
