A molecular phylogenetic analysis of the vampire moths and their fruit-piercing relatives (Lepidoptera: Erebidae: Calpinae).
Molecular phylogenetics and evolution, 2012Co-Authors: J. M. Zaspel, Reza Zahiri, Marjorie A. Hoy, Daniel H. Janzen, Susan J. Weller, Niklas WahlbergAbstract:Within butterflies and moths, adult hematophagy is limited to species within the vampire moth genus Calyptra. These moths are placed within the subfamily Calpinae, whose other members are known to exhibit a broad range of feeding behaviors including those that can be considered ‘piercers’ of fruits or other hosts and ‘tear feeders’. Here, we reconstruct a phylogenetic hypothesis of Calpinae using molecular data to test whether hematophagy in Calyptra arose from plant or animal-related behaviors. We use a Bayesian method of ancestral state reconstruction to determine the most likely feeding behaviors for the subtribes and genera within this lineage.

geographic distribution phylogeny and genetic diversity of the fruit and blood feeding moth Calyptra thalictri borkhausen insecta lepidoptera erebidae
Journal of Parasitology, 2014Co-Authors: Jennifer M Zaspel, Clare H Scott, Sharon R Hill, Rickard Ignell, V S Kononenko, Susan J. WellerAbstract:Facultative blood feeding on live animals or carrion is widespread within Lepidoptera. Male moths within the genus Calyptra are known to use their fruit-piercing mouthparts to occasionally feed on mammalian blood. The Palearctic species Calyptra thalictri is known to exhibit differential feeding behaviors that appear to be based on geographic location. This species is known to pierce fruit throughout its range but has recently been reported to also feed on human blood under experimental conditions in the Russian Far East. Here we document the distribution of this widespread species, reconstruct its evolutionary history, and calculate its genetic diversity for the first time. Recently collected samples are combined with museum specimens to model suitable environments for this taxon. Our findings suggest that while the blood-feeding populations are not monophyletic, there is geographical structure. Our analysis of macroclimate variables suggests that altitude and precipitation are the environmental variables most critical to habitat suitability in this lineage.

to be or not to be a vampire a matter of sensillum numbers in Calyptra thalictri
Arthropod Structure & Development, 2010Co-Authors: Sharon R Hill, Susan J. Weller, Jennifer M Zaspel, Bill S Hansson, Rickard IgnellAbstract:The mechanisms by which blood feeding in insects has evolved are unclear, primarily because there has been no access to species in which there is a mixture of same-sex blood feeding and non-blood feeding individuals. The discovery of a subset of male Calyptra thalictri (Lepidoptera: Noctuidae: Calpini) that blood feed under constrained experimental conditions, while the majority of these males do not, provides a unique opportunity to investigate members of the same species for potential root mechanisms leading to the ability to blood feed. Previously, C. thalictri populations revealed no morphological differences in the classical structures used for species identification in individuals that took a blood meal compared with those that did not. We report a description of the antennal sensilla and their distribution in male C. thalictri and describe an antennal sensillum distribution dimorphism between individuals that took a blood meal under constrained experimental conditions and those that did not. The number of olfactory sensilla, primarily sensilla coeloconica but also sensilla auricillica, is reduced in C. thalictri males that took a blood meal compared with those that did not. The selectivity of sensilla coeloconica olfactory sensory neurons was investigated. The sensilla coeloconica demonstrated sensitivity to fifteen vertebrate-related volatiles, including ammonia. We propose that the reduction in olfactory sensilla sensitive to vertebrate-related compounds may be correlated to an increase in the likelihood of a male C. thalictri to take a blood meal.
