The entire life cycle of the black webspinner is typically completed within a year. They are a hemimetabolous insect species, meaning that they have incomplete metamorphosis . During developmental stages the nymphs produce silk from silk glands.
Lipoptena cervi, the deer ked or deer fly, is a species of biting fly in the family of louse flies, Hippoboscidae.These flies are commonly encountered in temperate areas of Europe, Siberia, and northern China.
Adults have white hindwings and brown forewings, each with a dark streak, and a wingspan of 4 cm (1.6 in). [1] The abdomen is red or, more rarely, yellow. [1] Males have four large, grey-colored coremata behind them, which can exceed the length of the abdomen when inflated.

In insects, the chorion has a layer of air pores in the otherwise solid material which provides very limited capability for respiratory function. In Lepidoptera, the chorion layer above this air pore layer is lamellar with successive sheets of protein arranged in a particular direction and stepped so as to form a helical arrangement.
The development of each life cycle depends on the environmental conditions in which the larvae are feeding or being reared. It generally occurs "at 22-24°C, the first instar lasts 1-2 days, the second 1-2 days, and the third 3-4 days before pupation and a further 1-2 days before pupation."
Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds.In this family, the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic.
