The Singing Reaper: Diet, Morphology and Vibrational Signaling in the Nearctic Species Feniseca Tarquinius (Lepidoptera: Lycaenidae, Miletinae)*
MetadataShow full item record
A survey at fourteen sites in Eastern North America of populations of the carnivorous lycaenid butterfly, Feniseca tarquinius, confirmed that the sole prey item on Alnus rugosa (Betulaceae) for this species in these regions was Paraprociphilus tessellatus (Homoptera: Aphidoidea: Pemphigidae). Overwhelmingly, these aphids were tended by ants in the subfamily Formicinae. These results are compiled with all earlier records of prey aphids, their host plants and attendant ants for this species. SEM examination of a 4th instar larva of F. tarquinius supported Cottrell's (1984) observation that the dorsal nectary organ and tentacle organs are absent in the 4th instar of virtually all Miletinae. Larvae of F. tarquinius were found to produce substrate-borne vibrations that possess a long pulse length and narrow bandwidth when compared with other lycaenid calls. The possible function of these calls is briefly discussed.
