West Virginia | Butterflies and Moths of North America

Shykoff and Bucheli (1995) found that female flowers produced less concentrated nectar than males, but do not differ from males in nectar quantity; therefore females produce less sugar than males. They also found that nocturnal pollinators preferred male flowers. Brantjes (1978) found that Hadena bicruris, a noctuid moth that both pollinates and oviposits in the flowers of S. alba in Europe, uses petal odor to distinguish between the sexes of the flowers, choosing female flowers to oviposit in. These same olfactory cues could be used by moths in Virginia to detect the male flowers for visitation to extract nectar. However, in my study, moths visited flowers randomly with respect to flower sex. This could be explained by the equal nectar production of male and female flowers (Shykoff and Bucheli, 1995).

Gypsy moths (and other insects) are ectothermic, or cold-blooded, which makes them particularly sensitive to climatic changes (e.g. Logan et al. 2003, Vanhaven et al. 2007), because it is hard for them to compensate for an unfavorable climate. Gypsy moths require a climate warm enough for the adults to emerge, have time to mate, lay eggs and for the eggs to have some development prior to the onset of winter. At the same time, the winter chilling temperatures are also important for egg development. (See Régnière and Negalis 2002) Climate change is predicted to result in northern (Vanhanen et al. 2007) and western (Logan 2003) shifts in Gypsy moth change. Gypsy moth presence has declined in Virginia, most likely due to management actions; however changes in climatic conditions may reduce the suitable habitat in Virginia further over time. Decline of gypsy moths in Virginia also may be due to previous infestations that significantly reduced the oak population.
