The back two legs have a single set of white bands each. They display very long black antennae with a single distinct band of white near the tip, although the tip itself is also black. The wasp uses the white part of the antenna to palpate damaged wood and identify a suitable host. [4]
The larvae and adult versions of Pimpla rufipes feed on different food. The main hosts of this parasitic wasp are the large white butterfly (Pieris brassicae) and the spongy moth (Lymantria dispar). [14] The larvae feed on the hosts that have been through parasitisation, one example of which is the tomato moth, Lacanobia oleracea. [13]
The fully winged sawflies are 2−23 mm long. They are predominantly black but species of Chalinus, Mocsarya and Orussobaius are more or less metallic. Some species have a red thorax or abdomen and conspicuous white or golden pilosity. Many Orussus species bear white spots on the legs. The antennae of males are composed of 11, those of females ...
The middle and the rear legs are orange, but the femurs of the rear legs completely black. In the middle leg pair, the femurs may be completely black or with only black rear sides. The larvae are relatively large, with a length of 30 millimetres (1.2 in) and possessing 22 legs. [6] [7] They have a white body with black spots, and feed on ...
Eggs are white, opaque, and cigar-shaped, measuring about 0.5 by 1.8 mm. Creamy white larvae are cylindrical, with noticeable legs and pointed jaws. Larvae are active when removed from their tunnels. [ 4 ]
Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the prothorax. [2]
In fact they bury the carcasses of small vertebrates such as birds and mice as a food source for their larvae. In Nicrophorus interruptus both the male and female parents take care of the brood, quite rare behaviour among insects. The prospective parents begin to dig a hole below the carcass, forming the crypt, where the carcass will remain ...
The variety continuatus has additional black streaks on the fore wing below the costa, in cell, above inner margin, and in the marginal interspaces, but all the intergrades occur. Larva black, sparsely clothes with long hairs; head marked with white; a yellow dorsal line with a series of orange spots on it; prolegs pale.
