The table below shows the likely flight months for dragonflies (though remember that these will depend on the weather). The colours indicate whether species are likely to be common and widespread, locally common and scarce. Thanks to the photographers for donating their pictures.

*The first small red-eyed damselfly was found at Paxton Pits in late July 2004, at the east end of Cloudy Pit. This is believed to have been the first record for Cambridgeshire. Prior to a sighting in Essex in 1999, the species had never been seen in Britain, but they have colonised quickly and are now found at many sites in the Midlands and East Anglia.

A red-veined darter was seen on the edge of the quarry in June 2005, with several there in summer 2006. This Mediterranean species has been a rare migrant to Britain for several decades, but now breeds sporadically in Britain.

A female lesser emperor dragonfly was found at the edge of Island Pit in August 2007. First recorded in Britain in 1996, it is another species that has spread across southern and eastern England, and farther north.
