grey spider that looks like a black widow
Latrodectus geometricus Latrodectus geometricus, commonly known as the brown widow,[2][3] brown button spider, grey widow, brown black widow,[3] house button spider or geometric button spider, is one of the widow spiders in the genus Latrodectus. As such, it is a 'cousin' to the more infamous Latrodectus mactans (black widow).
Orb-weaver spider Many orb-weavers build a new web each day. Most orb-weavers tend to be active during the evening hours; they hide for most of the day. Generally, towards evening, the spider will consume the old web, rest for approximately an hour, then spin a new web in the same general location. Thus, the webs of orb-weavers are generally free of the accumulation of detritus common to other species, such as black widow spiders.
