Brown Recluse Spiders

The most recognized feature of the Brown Recluse spider is the violin pattern on the cephalothorax or, in other words, the location on the top side of the spider near the head. Thus they have been nicknamed the Fiddleback Spider. This characteristic is common in adult brown recluses, but some young brown recluse spiders do not have any contrasting pigmentation in the violin region.  Recluse spiders also have abdomens devoid of any coloration pattern. Their legs lack thickened spines but are covered with fine hairs.  The Brown Recluse spider does not build webs and is not native to California.

Typically, when venom is injected, the victim will experience an immediate redness which develops around the bite, then begins to disappear within a few hours. Very often, for the first 24 hours, the bite appears to be no worse than that of a mosquito; then it begins to blister in the center. Within 24 to 36 hours the blister breaks open leaving an open, oozing ulceration.

This ulceration scabs over within three weeks from the initial bite, leaving a permanent scar. If the bite is delivered in fatty tissue, the lesion may be very deep and extensive and not heal for two or three years. Systematic reactions to Hobo Spider poisoning include severe headaches, nausea, vomiting, soreness, and flu-like symptoms.

If you believe you have been bitten by a brown recluse spider, contact a physician immediately!
