Influence 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 کاملRefugia 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 کاملActivity patterns of a synanthropic population of the brown recluse spider, Loxosceles reclusa (Araneae: Sicariidae), with observations on feeding and mating
I recorded diel and seasonal activity patterns and behavior of the brown recluse spider, Loxosceles reclusa Gertsch & Mulaik 1940 in a free-ranging synanthropic population in northwestern Illinois. Recluse spiders are sit-and-wait predators that spend 85–90% of their nocturnal activity sitting motionless on a small network of silk they use for prey detection. Time not spent waiting for prey is ...
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...
