Abstract

Predation by aggressive mimicry in fireflies is known only in females of the Photuris pennsylvanica-versicolor group (it is doubtful that fireflies in the other group of the genus, i.e. P. congener and relatives, are predators as adults). Aggressive mimicry has been observed in 10 species, and circumstantial evidence suggests that such predation probably occurs in all species of the pennsylvanica-versicolor group, though there could be idiosyncratic exceptions. Probably most species prey on 2 or more species: P. versicolor preys on at least 11. Males and larvae of some Photuris spp. may also be aggressive mimics, but evidence is only suggestive. /// Predación por mímica agresiva en "fireflies" es sabido solamente en hembras del grupo Photuris pennsylvanica-versicolor (es dudoso que en el otro grupo del género de "fireflies", i.e. P. congener y sus parientes, sean predatores como adultos. Mímica agresiva ha sido observada en 10 especies, y evidencia circunstancial sugiere que tal predación probablemente ocurra en todas las especies del grupo de pennsylvanica-versicolor, aunque pudieran haber excepciones diferenciativas. Probablemente la mayoría de las especies son predatoras en dos o más especies: P. versicolor es predator por lo menos de 11. Machos y larvas de algunos Photuris spp. pudieron ser mímicas agresivas, pero la evidencia es solo una sugerencia.
