About Brown Widow
Brown Widow (Latrodectus geometricus) belongs to Theridiidae in the order Araneae. Its recorded origin status is introduced.
Natural history and identification
The brown widow constructs a sheltered silk retreat and guards its egg sacs. A study of this species found that maternal attendance helps defend eggs against parasitoids. The retreat can incorporate dry vegetation and remains of prey. These observations explain a reproductive behavior of the species; they do not measure its abundance or parasitoid pressure on Kauaʻi.
