Loa loa life cycle. Source: CDC. During a blood meal, an infected Chrysops fly introduces third-stage filarial larvae onto the skin of the human host, where they penetrate the bite wound. The larvae develop into adults that commonly reside in subcutaneous tissue. The female worms measure 40 to 70 mm in length and 0.5 mm in diameter, while the ...
The female fly will produce a single larva at a time, retaining the larva internally for all three instars. She then gives birth to the pre-pupal third-instar larva which promptly pupates and falls from the host deer. When the fly has completed its metamorphosis, the winged adult emerges and begins searching for a host.
The larvae of the splayed deer fly feed upon algae and organic matter in damp muddy soils. [6] The adult female flies feed on mammalian blood (including on roe deer), [7] in order for their eggs to mature properly. When they bite, they inject saliva with an anti-coagulating agent that prevent the blood clotting.
