Yes both very good food, Ephemeroptera are very soft and are eaten by all Paros. Chaoborus about the same, but they can be dangerous juveniles as there are predatory insect larvae. I feed both types common in my breeding pairs, which are many eggs. Unfortunately, both types may be obtained not always.

Black mosquito larvae come only from April again in front in the garden. Drausen in nature will be found black Mückenlarfen again under favorable conditions from February
