Field Notes

Description:

This spider was almost as big as a dime or even bigger and it was brownish black in color with yellowish markings. i found it inside the shed where it is dark and unfortunately for us some rain water had leaked inside making it Damp and humid.

Emma i recived a comment from you telling that Ismael has no acess to project noah,but the comment as been erased.so it's every normal? by the way,i wrote two times to the board about the seeds mission and hibrid mission and nobody respond me,i find that bizarre so i'am going to talk privetly in facebook to se if someone explane me why a mission with much more than 100 members is not considered global and others with much less than that are,i dont se the logic of this kind of decisions:(

Yup Cindy,this is "Steatoda triangulosa" I found a web which is very irregular and typical of this spider. These spiders are also known as False Black Widows. Thnx again Cindy. You are remarkable!
HemaShah
sounds like a good candidate for Latrodectus. Steatoda is another possibility (same family and they can look like widows).

It may be tricky without seeing the shape of the cephalothorax or the eye arrangement. Good luck!

I found this next to a big red widow in the shed. So Ia m wondering if it could be a male black widow,an immature black widow or false black widow? i am still researching and also looking into your suggestion Cindy. It will be a while before i get an ID.
HemaShah
Thnx Cindy for the suggestion.

I'm not 100% but I believe this is a Cobweb spider Steatoda triangulosa http://bugguide.net/node/view/6927

and i forgot to add that is was glossy and shiny. If you have seen a black widow,you would know what i mean.
