General Biology

Economic/Human Considerations

Camnula pellucida is mainly a grass feeder and sometimes causes severe damage to cereal crops. It is one of the primary pest grasshoppers in Canada. Since its numbers are known to be restricted by lower temperatures, increasingly warm temperatures in the north may lead to higher populations.

Decision Process Description: 
Draft rank by non-expert (S. Carriere) based on Catling (2008; R202) only (2010). Could be introduced? Reviewed by D. Johnson and C. Wiebe; no change (2014; H293). Reviewed by J. Miskelly (2017); no change. Reviewed by J. Miskelly in 2023 who recommended no change. Updated rank calculator scores shifted the S-Rank from S4S5 to S3S5 (still secure) (C. Singer, 2024).
