Refugia preferences by the spiders Loxosceles reclusa and Loxosceles laeta (Araneae: Sicariidae).
A variety of refugia were offered to different instars of brown recluse spiders, Loxosceles reclusa Gertsch and Mulaik, and a South American recluse spider, L. laeta (Nicolet), to determine whether they preferred certain types of refugia spaces. Variables included (1) crevice widths ranging from 3.2 to 21 mm, (2) horizontal and vertical orientations, and (3) new refugia or refugia that had silk...
متن کاملInfluence of spider silk on refugia preferences of the recluse spiders Loxosceles reclusa and Loxosceles laeta (Araneae: Sicariidae).
In a previous experimental study, recluse spiders Loxosceles reclusa Gertsch and Mulaik and Loxosceles laeta (Nicolet) (Araneae: Sicariidae) preferred small cardboard refugia covered with conspecific silk compared with never-occupied refugia. Herein, we investigated some factors that might be responsible for this preference using similar cardboard refugia. When the two Loxosceles species were g...

متن کاملSpiders of the genus Loxosceles (Araneae, Sicariidae): a review of biological, medical and psychological aspects regarding envenomations
Loxosceles spiders are of concern outside of the arachnological world because their bites can cause occasional necrotic skin lesions and/or systemic complications; these manifestations are known as loxoscelism. Once these spiders became well associated as medical entities, much notoriety was attained through the publication of medical case histories as well as tales of horrific wounds in the ge...
متن کاملThe genus Loxosceles Heineken & Lowe (Araneae: Sicariidae) in Cuba and Hispaniola, West Indies.
The three known species of the genus Loxosceles Heineken & Lowe from Cuba and Hispaniola are revised and two new species, Loxosceles maisi sp. nov. and Loxosceles mogote sp. nov., are described from the eastern region of Cuba. These new species are included in the reclusa group, and are considered close to Loxosceles taino Gertsch & Ennik as they have a greatly thickened male palpal tibia, a pr...
