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

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)

a pterous sepia ap se
apterous sepia (ap se)

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

spot

Two male mutants

with no wings and dark eyes

Black body is hard to see in this photo

although this part of the fly is quite dark

compared to the wild-type male at the top

dumpy sepia (dp se)

Two females, mutant on the left, wild-type on the right

Short dumpy wings,

different shape from

wild-type

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

sepia se
sepia (se)

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
