Hoplocryptus bellosus is a species of parasitic wasps , bees ( Apidae ) and grave wasps of the family Crabronidae parasitized.
features
Hoplocryptus bellosus is a slender parasitic wasp with a body length of approx. 6 to 9 millimeters. The head has long, thread-like antennae with 24 to 26 links. The head is rounded and slightly narrowed behind the eyes, the front edge of the clypeus is straight and has a small blunt tooth in the middle. The trunk is moderately dense to dense and relatively finely dotted, the mesopleurs wrinkled. The propodeum has two transverse strips, from the front transverse strip it is wrinkled in a reticulate manner. The last segment of the tarsi is not noticeably enlarged. In the forewing there is an areola (a small rhombic cell in the middle of the wing) with a broad front edge. The first limb of the free abdomen is narrowed in the shape of a pedicel and of moderate length with spiracles in or just behind the middle. The ovipositor's sheath is slightly shorter than the rails of the hind legs.
The basic color of the species is black. White drawing elements can be found on the label and as spots on the seventh and eighth tergites of the free abdomen, other white drawing elements of small dimensions are variable. The rest of the trunk and the propodeum are usually completely orange-red in color, rarely this is also black to varying degrees. Sometimes the first tergite of the gaster, sometimes parts of the second and third, are also orange, as well as the underside of the antennae flagella. Parts of the legs are also often colored red, so often parts of the thighs (femora) especially of the first and second pair of legs, the splints (tibia) of the first pair of legs (more rarely also parts of the second). The wings are clear.
Hoplocryptus bellosus differs from H. centricolor in that the last tarsal limbs are not enlarged and the white markings on the scutellum; from H. melanocephalus and H. bohemani a . a. due to different drawing.
Way of life
The larvae of the species are parasitoids of solitary bees and digger wasps. The known host species are mask bees (genus Hylaeus ), the mason bee Osmia leucomelana and gloomy bees of the genus Stelis ( Stelis minuta, Stelis ornatua ), as well as digger wasps of the genus Pemphredon ( Pemphredon rugifer ) and Trypoxylon ( Trypoxylon attenuatum ). Further host information is uncertain. All documented species nest inside twigs and plant stems, especially blackberries ( Rubus ) and roses ( Rosa ). The larvae of the host are pierced by the female through the wall of the brood cell (plant tissue) and covered with eggs. As far as is known, the larva overwinters in the host's nest.
distribution
The species is proven from almost all of Europe, from Scandinavia to the Mediterranean area, including Great Britain , also from the islands of Sicily, Crete and Cyprus and from Turkey and Iran.
Taxonomy
The species was first described by John Curtis as Cryptus bellosus . An earlier description as Ichneumon signatorius 1793 by Johann Christian Fabricius is not available because this name is preoccupied (this means that another species was previously referred to by the same name). Synonyms are Aritranis signatorius, Hoplocryptus pulcher, Cryptus fuscipes, Hygrocryptus thoracicus, Cryptas macrophyiae.
