Photos of Fruit Flies

Photos taken by Drs. Anne Galbraith and Nick Downey (2009)

female and male wild type
Female and male (wild-type)

Sex comb on male

No sex comb on female

Dark pigmented spot on

rounded abdomen of male;

male is also usually smaller

than female

sex comb
Sex comb

Found only on the two front legs of males


Dead wild-type male:

note the wings that are straight off from the body, a sign of death

(there are dead flies in other photos as well, by the way)

Wild-type fly with

wings and red eyes

Mutant fly with no wings and dark brown eyes

Wild-type female:

larger than the male, pointed

abdomen, no black spot

Wild-type male:

smaller than the female,

rounded abdomen, black

although this part of the fly is quite dark

compared to the wild-type male at the top

Note that the mutant also has sepia eyes but in this photo,

it is hard to see the color difference from wild-type

e bony vestigial e vg
ebony vestigial (e vg)

This is likely a mutant male based on

small size and what looks like the black

spot on the abdomen, but sex combs

would have to be found to

be certain

Wild-type female

Mutant female:

Note the vestigial (shriveled) wings

And dark body color compared to wild-type

Note the different

shades of eye color

in sepia mutants; the dark color

comes in with age

so more newly hatched

adults might have a

lighter brown color that can

be mistaken for wild-type red if

you’re not careful
