An excellent year with 19 of 22 species on the Warren list recorded; two to look for in 2022 are Cepero's Groundhopper and Dusky Cockroach; Rufous Grasshopper was however last recorded in the 19th century.
Common Earwig was the first species recorded on 21 February followed by Common Groundhopper on 17 April. Into May the first Dark Bush-cricket nymph of the year was recorded on 7th, a Slender Groundhopper on 8th was a good find, this species remains scarce on site. Field Grasshopper and Great Green Bush-cricket nymphs were active in the meadows from the 28th, with a Lesser Cockroach found in the dunes on the same date.

Speckled Bush-cricket on 2 June and an Oak Bush-cricket on 20 June were new for the year with Meadow Grasshopper from 7 July. By 18 July several other species had emerged with numerous Short-winged Conehead, Common Green, Mottled and Lesser Marsh Grasshopper, the Warren is one of the few sites for the latter species in Devon.
In August Grey Bush-cricket and Long-winged Conehead were found on 8th and several Tawny Cockroach arrived at light traps on 18th, the latter is another species rarely recorded in Devon.

The second record of Roesel's Bush-cricket, another long-winged male, was in Greenland Lake on 5 September. The first record was in July 2018. Hopefully this will become an regular species in the future as it is now established in Exmouth, following its expansion into Devon in recent years. The nationally scarce Lesne's Earwig from 12 September concluding the species list for the year.
The mild weather in autumn encouraged Great Green and Grey Bush-cricket to remain active up to 26 October and Field Grasshopper to 2 November.
