So, back to the drawing board... My friend returned with more adults and they laid eggs and now.....

But, I still am having trouble getting fruit flies from the pet store. I noticed my bananas had a nice halo of flies.... One way to rid an area, a room perhaps, of flies is to pour out a bit of dark red wine into a glass. The flies go in, get happy, and don't get out... So, with a small plastic spoon in the midst of the larvae, I pour the smallest amount of Merlot. I put just enough wine so that it attracts the fruit and vinegar flies but does not kill them. They drink. They mate. They lay eggs. They get drunk and and and ..... get to close to the larvae.... Happy larvae.
Life is so cruel.
I took these pictures in the afternoon sun as it peeked through the window. I have to sneak up on these guys to see them otherwise they disappear down their burrow.
