Brown widow spiders
Latrodectus geometricus, commonly known as the brown widow, brown button spider, grey widow, brown black widow, 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). L. geometricus has black and white patterns on the sides of its abdomen as well as an orange-yellow colored hourglass shape.
Their bites, though painful, are not considered to be dangerous.
