After a pupal stage, they emerge as adults in late spring and summer. While male deer flies collect pollen, female deer flies feed on blood, which they require to produce eggs. [5] Females feed primarily on mammals. They are attracted to prey by sight, smell, or the detection of carbon dioxide. Other attractants are body heat, movement, dark ...

The cycle of infection continues when a non-infected mango or deer fly takes a blood meal from a microfilaremic human host, and this stage of the transmission is possible because of the combination of the diurnal periodicity of microfilariae and the day-biting tendencies of the Chrysops spp. [5]
Examples are W. bancrofti, whose vector is a mosquito; night is the preferred time for blood collection. Loa loa's vector is the deer fly; daytime collection is preferred. [7] This method of diagnosis is only relevant to microfilariae that use the blood as transport from the lungs to the skin.
Blood culture bottle: Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator ...
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.

Chrysops caecutiens reaches a length of about 8.5–10 millimetres (0.33–0.39 in). [6] The mesonotum and the scutellum are glossy black with yellow-brown hairs. The compound eyes have red and green reflections, with dark spots.
