Many studies have been done on the Tsetse Fly because of their role in transmitting disease.

The Tsetse flies are having many broods per year (multivoltine), definitely producing about 4 generations every year,and up to 31generations total over their whole lifespan.

Tsetse flies are roughly look-alike to other big flies,such as the house fly,but can be differentiated by their various anatomy characteristics, 2of which are easy to observe.

Tse Tse flies fold their wings entirely when they are taking a rest with the result that one wing rests directly on top of the other wing over their chest/abdomen.

The biology of tsetse fly is relatively well understood.

Tse tse have been extensively studied because of their medical,veterinary,and economic importance,because the flies can be raised in a laboratory,and because the flies are relatively large,facilitating their analysis.

Tsetse Fly next become puparia small,hard shelled,oblongs with 2distinctive, small, dark lobes at one end.

Tse tse puparia are under 1.0 cm long.

Within the puparial shell, tse tse complete the last 2 larval instars and the pupal stage.

Tsetse Fly then emerge as adult flies.

Tsetse Fly adults are relatively large flies,with lengths of ½ –1½ cm, and have a recognizable shape or bauplan so they can usually be distinguished without trouble from other flies.

Tse tse have large heads,distinctly separated eyes,and unusual antennae.

The tse tse thorax is quite large,while the abdomen is wide rather than elongated and shorter than the wings.

tse tse fly

The word 'Tse Tse'comes from Tswana, a language of southern Africa,and,in that language,the word means fly.

Recently'tse tse'without the'fly'has become more common in English, particularly in the scientific and development communities.
