Quick answer
Brown Recluse Spiders feed on insects and other small arthropods, adjusting with season, age, and what is abundant in Dark undisturbed spaces — attics, closets, sheds, and woodpiles. That label is a preferred pattern, not every item an individual might sample.

Brown Recluse Spider diet overview
Brown Recluse Spiders (Loxosceles reclusa) are best summarised as Carnivore — insects and other small arthropods. Anatomy and habitat (Dark undisturbed spaces — attics, closets, sheds, and woodpiles) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How brown recluse spiders find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Brown Recluse Spider role in the food web
As predators or scavengers, brown recluse spiders move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild brown recluse spiders. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Reclusive habits
Brown recluses avoid open spaces and daylight, spinning irregular webs in undisturbed corners rather than catching prey in orb webs. They hunt small insects at night and tolerate crowding — dozens may share a hidden void in infested buildings.
Violin marking and identification
The dark violin-shaped mark on the cephalothorax helps identification, though similar marks occur on harmless species. Six eyes in three pairs (most spiders have eight) is a diagnostic feature. Misidentification is common outside their native range.
