Very similar to the much commoner A. fallenii, this species has always been a great breckland rarity and was thought to be extinct for many years, before its rediscovery in 2011. It has since been found at various sites in Suffolk and Norfolk.
Best distinguished from A. fallenii by the pronotum, which lacks the two backwards pointing rows of pale spines. The third antennal segment is also thickened towards the tip.
There are no apparent ecological differences between the two Arenocoris species, both of which feed on Common Storksbill Erodium cicutarium in dry, sandy habitats.
