One of the signs of a healthy waterbody such as Manchaug Pond is the existence of Mayflies. Short lived, they mature and emerge in June then molt, mate, the females lay eggs and finish their life cycle just in a couple of days. They are a very important ingredient in the food chain for fish and birds. Contrary to what they may look like, they do not sting or bite.
It is a welcome sign that spring has arrived when we see them each year!
