Non-biting midges (Chironomidae) spend most of their lifetime in an aquatic environment. Adults emerge from their pupae in the water, usually at sunset and only for a short time, in order to mate and oviposit. Females return to the water only once (in most of the species) to lay eggs. Gelatinous egg masses are attached to objects at water level. We found one such gelatinous chironomid egg mass in our local moina species culture:
