Chlorion hirtum is a species of digger wasps (Spheciformes) from the family Sphecidae . The distribution area of this large and strikingly colored wasp includes North Africa and the Arabian Peninsula . So far nothing is known about the biology of the species.
features
size
Chlorion hirtum belongs to the large species of the genus, males from Egypt had a body length of 21–33 mm, females (26) 30–38 mm.
coloring
The wings are yellow, the forewings show a very distinct dark brown tip area, especially in females. The hind wings have a less strong, dark tip area, which is occasionally only very indistinct. The head, thorax and abdomen ( gaster ) are black. The head and the pronotum ring occasionally show rust-red areas. The gaster sometimes shows a slight metallic sheen in males, but it is always missing in females. The mandibles are blackish rust-red. The antennae are solid rust yellow or only colored at the base and then darker on the top with black tips. The legs are black, but the tibia and tarsi are more or less dark rust-red, especially those of the front legs. Males from the Sinai Peninsula show bright rust-red forelegs from the ends of the femur . Females are overall darker than males with much darker or missing rust-red parts. The hair on the head, thorax, petiolus and coxae is black.
morphology
The hairiness is stronger than in other species of the genus, especially that of the males. In males, the front edge of the frontal plate ( clypeus ) has three teeth. Feeler link 3 is significantly shorter than link 4. The pronotum is striated across. The first sternite has long hairs, sternite 2 and the other sternites have only individual hairs.
In females, the leading edge of the clypeus is only indistinctly sawn, the entire surface of which is very finely sculpted with points with individual, larger and hairy point pits, which are far apart. Antenna 3 is almost as long as the eye relief. The thorax shows a dense microsculpture with fine black hair over the entire mesonotum , which is often worn in older specimens. The dotting of the mesopleur is dense but quite flat.
Pulawski does not recognize any subspecies.
distribution
The range of the species includes North Africa and the Arabian Peninsula . The species has been detected in Africa so far in Northeast Africa in Ethiopia and Egypt and far from the rest of the area in Algeria , also in Israel , Jordan , on the Red Sea coast in Saudi Arabia , in Oman and in the United Arab Emirates and on Persian Gulf .
Way of life
As with most species of the genus Chlorion , nothing is known about the way of life of Chlorion hirtum . The four chlorine ion species that have been studied in more detail so far use crickets or cockroaches as larval food .
