We tested natural and factitious host insects for their physiological responses to stinging by the gregarious ectoparasite, Euplectrus plathypenae Howard, and observed hosts injected with tissue from the lower reproductive tract of the female parasitoid. Tests included eight recorded lepidopteran hosts and larvae of 36 other species of Lepidoptera not previously recorded as hosts, plus 19 species in six other orders. The arrestment of development produced by E. plathypenae was expressed in all natural hosts and in most, but not all, insects outside the natural host range of the parasite.
