Brown widow spider
by: Moni

Thank you Anonymous for the great website.

It does look like this cobweb spider is a brown widow spider. The egg sac having spikes is a great identifier.
To clarify, yes the brown widow does have more potent venom than the black but it is considered less poisonous as they do not inject as much venom as the black widow.
" According to experts at the LSU AgCenter, brown widow spiders can be found in brush piles, crawl spaces, and under chairs, flower pots, eaves and porch railing. However, brown widow spiders are shy, less likely to bite and deliver less venom in their bites than black widow spiders."

Just like a Black widow, except Brown and more venomous. The picture and egg sac shown is exactly what both of them look like. See this link: http://sarasota.extension.ufl.edu/IPM/BrownWidow.htm
Cobweb Spiders

I believe your spider is a cobweb spider. Spiders are not my specialty...they are not insects.
Cobweb spiders are common house spiders, but also include the black widow. They are similar to orb weaver spiders but their web is messy rather than and even circular web.
Cobweb spiders are common and can be found almost anywhere that they can find weeds, fences, trees, walls, or other upright structures to build their webs. Cobweb spiders are predators, and eat anything that gets trapped in their webs. Most web-building spiders, including cobweb spiders tend to have poor vision. They can "feel" prey when it gets caught in their webs.
Hope that helps.
