I photographed this today in the warehouse i work in hiding behind a box
Hi, it might be Latrodectus hesperus.
There are a few black widows with the hour glass but this is the 1st one ive seen this color
The hour glass markings on widows are on the ventral surface. Your photo is dorsal. If I’m correct that this is a western black widow, it is a juvenile. The colors and patterns vary with gender and developmental stage. Mature males have a dorsal row of orange-red marks. Mature females usually have a row of white dorsal marks like: ( ) ( ) ( ) except sideways, down the abdomen. The hourglass on this species is reddish orange.
