Arphia conspersa occurs early in the spring when few collections
were made. It is found at all elevations except the highest mountains.
Late instar nymphs overwinter and become adults in May and June. Adults
can be found later in the year at higher elevations. Eggs are laid in mid
summer and hatch before fall. In some areas development may take two years.
This species prefers grasses and sedges but feeds on some forbs. It rarely
is numerous enough to damage forage. Adults occur early in the year when
rangeland plants are growing vigorously.
