title: Thermoregulatory mechanisms in Sarcophaga.
abstract: The flesh fly, Sarcophaga, is frequently seen feeding on flowers during periods of high radiation when other flies of comparable size avoid exposure because of the dangers of overheating. Sarcophaga is able to maintain its intermittent flower visits due to a cuticle of high thermal reflectance, giving low intrinsic heating rates, and to an ability to shunt blood between thorax and abdomen according to its needs. The fly thus achieves partial thermoregulation and can keep its body temperature within the preferred range for longer periods than its potential entomophilous competitors.
