Notable range shifts of some Orthoptera in Yorkshire

摘要

2019 has been an interesting year for many species in terms of shifting distributions and none more so than two orthopterans from the Tettigoniidae family (bush-crickets). Long-winged Cone-head Conocephalus fuscus - a relatively recent arrival to Yorkshire - and Roesel's Bush -cricket Metrioptera roeselii have both shown significant northward range expansions of up to 80km over the last year (see Figure 1 opposite). Both are considered Rationally Scarce.
