There are a few out there that sell bulk Fruit flies. The one I use is the orginal Drospohila INc. Jerry Tressler. His web page is http://www.jtresser.com/drosophila.html His phone number and e-mail is on the page as well.
:Went to check my baby quad eggs at 18 weeks and six were out of their shells. I ordered four cultures this week. The past two clutches the babies hatched out at 22 weeks. This leaves me in a serious bind as the cultures will not produce anything for at least two weeks or more.
:Does anybody know of a business that sells established fruit flies culture with hundreds of adult flies. Any thoughts would be helpful. Thank you
