Wingspan 10-12mm. This small fly which rests with its wings in a tentlike fashion and resembles a brown lacewing is actually a Spongefly from the family Sisyridae within the order of Neuroptera. Note the antennae are completely dark compared to other similar species of which there are three in Britain within the same genus Sisyra.
The larvae are entirely aquatic and feed within the tissue of freshwater sponges. This is the most common and widespread species encountered, and is seen in association with slow-moving or static water. The adults are seen May to October.

I love the angle of the shot. Makes the wing span look very interesting – in fact, it looks almost like an old penny.

Nice to see all the details up close! I think we may have this one (or a very similar spongefly) in the USA that I see in the spring.

Thank you, Annie 🙂 Very interesting to know you may have one over there on the other side of the pond, too.
