Sceliphron spirifex (Linnaeus) (Mud Dauber)

(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera; Superfamily: Apoidea; Family: Sphecidae; Subfamily: Sceliphrinae; Genus: Sceliphron)

Sphex spirifex Linnaeus, 1758.  Lectotype: southern Europe: no specific locality (Linnean Society, London), designated by Day, 1979.

Diagnosis Superficially similar to Chalybion spinolae, but distinguishable by the matt black body (Chalybion spinolae has a metallic blue lustre to the body) and colour of the femur and tibia of the front and mid legs, which are yellow and black (reddish brown in Chalybion spinolae). Females are also easily separated by the black antennae (Chalybion spinolae females have reddish-orange antennae, but the males have black antennae). The petiole is relatively longer. The form of the propodeum is distinctive: there is an anterior central raised area bounded laterally and posteriorly by a shallow excavation. The nest construction for these two species is also very different (see biology below).

Sceliphron spirifex can only be separated reliably from S. quartinae by the shape of the hind coxae. The scapes (first visible segment of the antennae) are black in S. quartinae and dirty yellow in S. spirifex.

Distribution Belgium, Bulgaria, Canary Islands, Czechoslovakia, Egypt, Ethiopia, France, Greece, Italy, Kenya, Lebanon, Liberia, Libya, Mozambique, Nigeria, South Africa, Spain, Sudan, Tanzania, Toscana, Turkey, Uganda.

Biology

These wasps are Mud daubers building their mud nests in a variety of sheltered situations including inside and around houses. Females construct a nest comprising several adjacent tubes made from mud. They prey on a variety of spiders and mass provision the single cells with an egg laid on the first spider. The cells may be covered with an outer layer of mud providing extra protection to the developing larvae (Bohart & Menke, 1976). Prey are predominantly Orb web spiders, Araneidae (Araneaus, Argiope, Caerostris, Cyclosa, Isoxya, Nephila), but Theridiidae and Zodariidae are also captured (Gess & Gess, 2014)
