Identifying it in Arkansas

The bite itself is unimpressive — a pinprick and two faint punctures. What identifies it is what follows: pain that spreads from the bite into large muscle groups, classically severe abdominal cramping that has been mistaken for appendicitis. The spider is identifiable by the red hourglass on the underside of a glossy black abdomen.

Locally, the species most often confused with it are honey bee sting, brown recluse spider bite, carpenter ant bite — all of which are also recorded in Arkansas.

Seek medical care if

  • severe muscle cramps in the abdomen, back or chest
  • sweating, nausea, rising blood pressure
  • any suspected bite in a child, an older adult or during pregnancy — seek care

Season in Arkansas specifically

Records in Arkansas concentrate in May, August, September, October, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Arkansas runs March to November.

Because woodpiles, sheds, meter boxes, garden furniture, under eaves — undisturbed dark corners, exposure in Arkansas tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.

Care

  1. wash the area and apply a cold pack
  2. seek medical care for anything beyond mild local pain — antivenom exists and pain control matters
  3. do not apply a tourniquet or attempt to cut or suck the wound
