Thanks guys,
Indigo, those are indeed wingless fruit flies. I culture several varieties of flightless and wingless D. melanogaster and D. hydei.
The D. hydei have wings, but they are genetically paralyzed and can not fly.
I make several cultures of them every couple of weeks and sprinkle them out of the containers onto my CP's.
The Neps usually get misted or sprayed down first, because insects have a difficult time getting any kind of traction on a wet peristome, which you all know are very slippery when wet.
The fruit flies' tendency is to climb to the highest point, and they usually end up in the pitchers, after failing to successfully negotiate the peristome.
And the plants luv 'em.
