In a field experiment, we investigated fecundity costs of mobility in a non-migratory, wing-monomorphic grasshopper, Stenobothrus lineatus. We found that individual egg-laying reduces with increasing mean daily activity radius and were able to demonstrate that mobility within the habitat – as induced and selected for by foraging, thermoregulation, predator escape, shelter seeking and reproduction – can have immediate fecundity costs.
