I found this cobweb spider in my garden, it has been really difficult to me to identify the scientific name of this species. I need help, this is the link to the photo: https://mobile.twitter.com/PhillipJagger/status/255481575909756929?photo=1 , the black spot in the white back, it's characteristic of this species. Thank You

Not all spiders are hard to identify. The genus latrodectus family is easy to identify to me. I think that might be that I study them all the time or it's just easy.

Gus, I'm not an expert on spiders, and get my identifications from www.bugguide.net After seeing quite a few, I do get familiar enough with them to be able to identify some to species, more to genus, and most to family.

I'm curious about your species level identifications. Are you an arachnologist? Identifying to even the genus level is pretty hard. I just got a copy of Spiders of North America (Ubick et al. 2005). Many paths through that key involve disection of gonads or other examinations that can only be performed on a dead spider under a microscope. If you aren't keying these out scientifically, you should at least note that in your description... If you have a reference for making species level identifications on live spiders I'd love to know... In any case beautiful pictures either way! Immatures are also a vexing problem not covered by Ubick. -Gus
