1146. This spider is in the family Theridiidae (cobweb/comb-footed spiders); likely in the genus Latrodectus, such as the western black widow (L. hesperus; see http://www.royalalbertamuseum.ca/natural/insects/bugsfaq/pics/blackwid.jpg ). False black widow/cupboard spiders in the genus Steatoda are similar in overall appearance, but females in this genus usually have a prominent pale transverse band near the front of the abdomen, and no such marking is visible in the photo. Bites from Steatoda can be painful, and bites from at least one species in this genus (S. grossa in Australia) may require medical attention. As a small child, I received a very painful bite from one of these spiders (likely S. borealis) that left a lasting impression. It was a long time before I picked up another spider!

White crab spider

This is a crab spider (family Thomisidae); it resembles Misumessus oblongus – see http://tinyurl.com/93ouk69 for an image. All crab spiders are harmless to humans.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

 This is another fishing spider (family Pisauridae) in the genus Dolomedes. It is harmless to humans, although a specimen as large as this one could deliver a painful bite if mishandled. Ed Saugstad, retired entomologist; Sinks Grove, WV. 

This appears to be a male of the species Tegenaria Gigantea, AKA the Barn Spider or Giant House Spider.
Reference: http://en.wikipedia.org/wiki/Tegenaria_duellica . It is large, fast, and scary looking, but harmless. The males are seen far more often than the females, as the females tend to stay in nests of silk under objects outside, and the males wander about looking for them. The large ‘fist’ shaped appendages in front of its front legs are its pedipalps, the spider’s version of the penis. It is a close relative of the far more rare Tegenaria Agrestis, AKA the Hobo Spider.  Scott S.

This appears to be a male spider in the family Agelenidae (funnel web/grass spiders), likely in the genus Tegenaria (see http://www.washington.edu/burkemuseum/spidermyth/images/gigantea.jpg  for an image). Males in this family often wander quite some distance from their web, and then come to human attention when their wandering results in their accidental entrapment in tubs and the like. In spite of their appearance, they should pose no threat to human health. One species in this genus, the so-called ‘hobo spider’ (Tegenaria agrestis), has been implicated in cases of slow-healing ulcers (necrotic arachnidism) following a bite, but some controversy still exists on this subject. See http://www.xs4all.nl/~ednieuw/Spiders/Agelenidae/Agelenidae.htm for much more information on this group of spiders. Ed Saugstad, retired entomologist, Sinks Grove, WV.

This is a mygalomorph spider (the group to which tarantulas, etc. belong), possibly a male in the genus Antrodiaetus, see http://tinyurl.com/j3oluh9 for an example. Males of these spiders often are found wandering about, apparently in search of a mate, while the females usually are found in their burrows. Ed Saugstad, retired entomologist; Sinks Grove, WV.
