July 06, 2006.
The adults were presented in my thread:
http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=2235
I think that Drosophila cf. repleta were more numerous.
Size 2-3mm, almost swimming on the substrate.

These were leaving the substrate, ready to pupate.

The puparium, size 2-3mm, too.

Just let us know when adults emerge which of the species it was. ;)

OK - I hope I'll be able to protect them from my (female) kin ;)

No :o (they would rather make me taste the stuff, most of my activities with 6-legged creatures is such a nuisance for them :(), from trying to get rid of them - they are anxious whether the winged plague will spread. Currently they simply don't like the smell.

Yesterday some flies have emerged. The vast majority was smaller D. cf. melanogaster with just a few bigger D. cf. repleta (hydei).

Another view + head.

Well maybe it's more than one species or males/females (dark spots on abdomen are different, and some have dark bristles on tarsi I).
The bigger fly.

The top set of adults are a species of the
Drosophila melanogaster group (first two pictures of females, next series of males), the bottom is
D. repleta. Note the palish spots lateral on the abdomen and the somewhat darked apex of the first costal section.

OK thanks a lot Paul. Strange, I remember that D. repleta were more numerous than D. melanogaster among the progenitors, while the situation is contrary among the spawn.

a. Maybe more flies will emerge.
D. repleta is a larger species and may requie more time for development.
b. The substrate was less suitable for development of the
D. repleta larvae. Even the presence of many
D. 'melanogaster' larvae may make the substrate unsuitable.
c. Maybe adults of
D. repleta were there but did not oviposit.
