Numbers
3 spp. in our area(1), 35 total(2)
Identification
S. cementarium is by far the most widely distributed and common of the two. It can be distinguished by a broad yellow band at the base of the hind-tibiae, and upper 3 metatarsomeres yellow.
S. assimilis has dark metatarsi and metatibiae mostly black, usually with a yellow streak on the basal inner third/half (often less pronounced in the female; cf. key couplet 10), and in our area is only known from Texas.
S. curvatum-or-deforme, from Europe, has been recently discovered in Quebec.
Range
in our area, one sp. widespread, another in TX(1), one European species introduced in Quebec.
Remarks
These are the common black and yellow mud-daubers which build mud cells in sheltered situations. Each cell is stored with a number of small, paralyzed spiders.(3)
