Stable Fly - prestomal teeth

Post by NikonUser »

This close relative of the House Fly is sometimes called the biting house fly (top image). The proboscis is a disproportionally elongated rigid tube (middle image). At the tip it has modified its fleshy labella into a densely horny ball accommodating 2 sets of 5 well developed prestomal teeth (bottom image). These are the main implements used for cutting into mammalian skin/flesh.
Both males and females are vicious blood suckers.

Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
Oliver Wendell Holmes, Sr
