This study compiled 33 verified spider bites from the state of Oregon (USA). The initial goal was to amass a series of bites by the hobo spider to assess whether it possesses toxic venom, a supposition which is currently in a contested state. None of the 33 bites from several spider species developed significant medical symptoms nor did dermonecrosis occur. ⋯ There were 10 bites from three genera of funnel web spiders of the family Agelenidae including one hobo spider bite and one from the congeneric giant house spider which is readily confused as a hobo spider. The hobo spider bite resulted in pain, redness, twitching in the calf muscle and resolved in 12 h. Also generated from this study were possibly the first records of bites from spiders of the genera Callobius (Amaurobiidae) and Antrodiaetus (Antrodiaetidae), both with minor manifestations.

Brown recluse spiders are one of two types of spiders in the United States that can cause significant tissue damage and, in rare cases, death. Brown recluse spider bites are most often benign and self-limiting, but in a few cases can cause severe necrotic skin lesions.

Case ReportsPriapism after western black widow spider (Latrodectus hesperus) envenomation.
Priapism in children after a black widow spider bite is a rare phenomenon with only a few case reports noted in the literature. Black widow bites are commonly associated with pain, muscle cramping, hypertension, and tachycardia. ⋯ Treatment with antivenom for priapism is not well described; however, it has been noted to resolve priapism in the few cases that have been reported. We present a case of a 3-year-old boy who was bitten by a black widow and presented with abdominal cramping and priapism.
