Do black widow spiders have any markings on their backs?

Answer 1

Yes, black widows are very deadly and is probably the most venomous spider in the world. Despite their deadly venom, there aren't much deaths per year by these Spiders as long as humans get immediate medical intention.

Answer 2

The female black widow spider usually has a prominent red hourglass figure on the underside of its abdomen. Note that not all adult female black widows exhibit the red hourglass on their abdomen-some may have a pair of red spots or have no marking at all, but any markings that are present are bright red.

Several related "widdow" spiders from the Latrodectus genus of spider, in the family Theridiidae (to which all black widdow species belong) have similar markings but not all of them are on the underside of their abdomens - for example the redback spider of Australia has a red stripe on its back (which is where it gets its name), and the Latrodectus pallidus - which has the English name of "white widdow spider" has no marks at all, rather the white widow spider is light-coloured, with colouration ranging from beige to white, though with darker legs.
