No invertebrate specialists have ever studied the reserve and the recorded species are therefore, limited and restricted to such species (or groups) that can be safely identified by keen amateurs.
Nevertheless, the Odonata and Orthoptera are probably thorough. The former group (the dragonflies and damselflies) are not well established in the meadow (though Common Darter oviposit in the brook) and Migrant Hawker nymphs have been found in the ponds, other recorded species are probably wanderers.
Keyworth Meadow had its five minutes of fame in 2007 when the first Long-winged Conehead for Nottinghamshire was discovered there.
