After reading the article on collecting mosquito egg rafts, I`m able to collect 10-20 egg rafts a day. I`m keeping the larvae in rather small containers until they get to a desired size to feed to my newt larvae. It seems like it is taking longer than expected for the mosquito larvae to grow. I have also noticed that a few of the mosquito larvae will grow much faster than the majority. Could overcrowding be hindering the growth of the mosquito larvae? Has anyone experienced the same problem?
