Twenty one species of dragonfly and damselfly have been recordred at Chew, which isn't bad, considering that the lake doesn't support any real specialities, and even one or two species which might be expected to occur (both residents and migrants) are missing from the list.

It seems that the next addition could just as likely be a continental species as one which has wandered a few miles from the Mendips or Somerset levels. Species which breed within a short distance include Common Hawker, Black Darter, Downy Emerald, Golden-ringed Dragonfly, Keeled Skimmer, Hairy Dragonfly and White-legged Damselfly. The last species is probably favourite to be the next to go on the list as it occurs on the River Chew at Chew Magna; there have been unsubstantiated claims.

In the third column, B indicates that the species breeds every year, and b indicates irregular or possible breeding.
