The Hacklemesh Weaver spider builds a tangled mess of spider silk into a fluffy web that traps insects.
This small brown spider is sometimes mistaken for a Brown Recluse, but it lacks the dark 'violin' silhouette. If there is a visible pattern at all on the abdomen, the Hacklemesh Weaver would have a series of pale chevrons on their abdomen never seen in the Brown Recluse. Like almost every North American spider, it is venomous, but it is not poisonous like the Recluse. Hacklemesh Weavers are not aggressive.
These are small spiders that build silken webs that they tease out into a big mass with one of their legs, like a hair stylist with a comb. Unlike orb weavers whose intricate spiral strands create an almost invisible web, hacklemesh webs lack symmetry and design. Despite their lack of elegance, they are still quite effective at catching insect prey.
Hacklemesh Weavers can be found in woodlands under stones and logs, on tree bark or on branches. They sometimes wander into basements and cellars to make a home. Females lay fertilized eggs in a silken sac that is kept on the web and covered in whatever debris she finds nearby.

Size (Adult; Length): 6mm to 11mm (0.23in to 0.43in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
Pedipalps: Small appendages near the mouth used as taste and smell organs.
Cephalothorax: Contains eyes, head, mouthparts, and legs.
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).
