Overview of the focal grasshopper species and observed shifts in their phenology and abundance between 1959–1960 and 2006–2008 (data from Nufio et al., 2010; Buckley et al., 2013b)

Species	Dispersive	Thermal adaptation	Seasonal timing	Phenology (↓ earlier)			Abundance

Melanoplus boulderensis	No	Cool	Early	↓	↓	≈	↓	↓	≈
Camnula pellucida	Yes	Warm	Middle	↑	↓	↓	↓	↓	↑
Melanoplus sanguinipes	Yes	Generalist	Late	↑	↑	a	↓	↓	a

^aLow abundance during initial time period prevents comparison.
