The effect of prey behaviour on prey acquisition by a predator was examined in the laboratory, using three larval mosquitoes. Aedes albopictus was acquired by the predator, Toxorhynchites towadensis , at a higher rate than Orthopodomiya anopheloides. Toxorphynchites towadensis was a sit‐and‐wait predator. Aedes albopictus was more active than O. anopheloides. Orthopodomiya anopheloides ran away before the predator attacked, but A. albopictus did not. The escape ratio in O. anopheloides was higher than that in A. albopictus . These results suggest that the difference in the prey acquisition ratio by the predator between prey species is caused by different behavioural patterns of the prey to the predator.
