Parasitoids of European butterflies
Parasitoids are insects (mainly Hymenoptera and Diptera) whose larvae develop by feeding on the bodies of other arthropods (mainly immature insects) and the adults are free living. They are of immense importance in practically all terrestrial ecosystems because of their impact on the population levels of their hosts. In contrast to the considerable attention paid to European butterflies their p...
متن کاملWhite butterflies as solar photovoltaic concentrators
Man's harvesting of photovoltaic energy requires the deployment of extensive arrays of solar panels. To improve both the gathering of thermal and photovoltaic energy from the sun we have examined the concept of biomimicry in white butterflies of the family Pieridae. We tested the hypothesis that the V-shaped posture of basking white butterflies mimics the V-trough concentrator which is designed...
متن کاملYellow and the Novel Aposematic Signal, Red, Protect Delias Butterflies from Predators
Butterflies of the South Asian and Australian genus Delias possess striking colours on the ventral wings that are presumed to serve as warning signals to predators. However, this has not been shown empirically. Here we experimentally tested whether the colours of one member of this diverse genus, Delias hyparete, function as aposematic signals. We constructed artificial paper models with either...
متن کاملAre Women Obsessed with ‘White’ Weddings?

The researchers employed a qualitative case study approach to examine the phenomenon. Thirty single women at the Kwame Nkrumah University of Science and Technology, Ghana were sampled using the purposive sampling technique. ...
متن کاملUnexpected layers of cryptic diversity in wood white Leptidea butterflies.
Uncovering cryptic biodiversity is essential for understanding evolutionary processes and patterns of ecosystem functioning, as well as for nature conservation. As European butterflies are arguably the best-studied group of invertebrates in the world, the discovery of a cryptic species, twenty years ago, within the common wood white Leptidea sinapis was a significant event, and these butterflie...
