Perching heights and nocturnal communal roosts of some tiger beetles ( Coleoptera: Cicindelidae) in southeastern Peru.

When disturbed, diurnally active species of tiger beetles flew from the forest floor, where they foraged, to temporary perches in the vegetation. Height of perch was correlated with size of species. At night, these species roosted for 10-12 hr at the same height as their temporary daytime perches. Some species congregated nocturnally on communal roosts of 2-9 individuals during the early rainy season. Species from sandy edges of rivers roosted on grass blades at night. -from Authors
