So, I started a culture on the 12th of this month, I see a lot of larva and a lot of pupae on the sides of the container, however, I do not see a lot of flies in the culture. Does this mean that the culture is no good? Are they hatching and I just don't see them or what? I noticed larva about a week and a half ago and pupae maybe a week ago. The numbers of pupae are increasing, but I haven't noticed any increase in flies really.
