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 کاملPeriodicity of Molting and Resumption of Post-Molt Feeding in the Brown Recluse Spider Loxosceles reclusa (Araneae: Sicariidae)
The periodicity of molting and resumption of feeding after molting was investigated in the brown recluse spider, Loxosceles reclusa Gertsch and Mulaik (Sicariidae). Spiders molted almost every hour of the day but there was a tendency to molt more frequently between 8 A.M. and 1 A.M. Spiderlings resumed feeding after 20 hrs post-molt with feeding occuring more frequently around the 43rd hour and...

متن کاملThe Present Status and a Review of the Brown Recluse and Related Spiders, Loxosceles spp. (Araneae: Sicariidae), in Florida1
INTRODUCTION: The brown recluse spider, Loxosceles reclusa Gertsch & Mulaik (Figs. 1-2, 6), is frequently reported in Florida as a cause of necrotic lesions in humans. For example, in the year 2000 alone, Loft (2001) reported that the Florida Poison Control Network had recorded nearly 300 alleged cases of brown recluse bites in the state; a subset of 95 of these bites was reported in the 21 cou...
