- Easily mistaken for the “brown recluse” (Loxosceles reclusa) or other species in the genus.
- This spider lives mostly under stones, in abandoned rodent burrows, and other natural refuges outdoors.
- Egg sacs of related species average between 30 and 50 eggs per sac, with rates of successful hatching varying from 40-80% (Vetter 2008).
- This spider’s venom contains sphingomyelinase D, a necrosis-causing enzyme.
- This is a medically significant species: venom is potentially dangerous to humans. Reactions can vary from “unremarkable” (little, if any, damage and are self-healing) and “mild” (redness and itching, but usually self-healing) to “dermonecrotic” (a necrotic skin lesion that requires medical intervention) or, very rarely “systemic” (affecting the vascular system and potentially fatal). The potential for bites is slim, and can be largely avoided by taking simple precautions, and the majority of verified cases fall into the first two categories (unremarkable or mild). Most importantly, many other medical conditions can produce the skin lesions so often wrongly attributed to Loxosceles or other types of spiders. Please consult Rick Vetter’s 2008 article for a list of these. Misdiagnosis can lead to worse problems than a mere spider bite (if the actual cause is MRSA, for example).
