Chromosome number evolution in skippers (Lepidoptera, Hesperiidae)

Lepidoptera (butterflies and moths), as many other groups of animals and plants, simultaneously represent preservation of ancestral karyotype in the majority of families with a high degree of chromosome number instability in numerous independently evolved phylogenetic lineages. However, the pattern and trends of karyotype evolution in some Lepidoptera families are poorly studied. Here I provide...

Functional constraints on the evolution of long butterfly proboscides: lessons from Neotropical skippers (Lepidoptera: Hesperiidae)

Extremely long proboscides are rare among butterflies outside of the Hesperiidae, yet representatives of several genera of skipper butterflies possess proboscides longer than 50 mm. Although extremely elongated mouthparts can be regarded as advantageous adaptations to gain access to nectar in deep-tubed flowers, the scarcity of long-proboscid butterflies is a phenomenon that has not been adequa...

Diel activity and reproductive isolation in a diverse assemblage of Neotropical skippers (Lepidoptera: Hesperiidae)

A sample of over 400 co-occurring species of Neotropical Hesperiidae attracted to artificial lures was used to test for temporal structure among species and explore potential consequences of temporal partitioning within assemblages. Five years of intermittent transect samples at the same site revealed that diel activity was significantly partitioned among subfamilies, genera and species within ...

Patterns of Genetic Variation Between the Checkered Skippers Pyrgus communis and Pyrgus albescens (Lepidoptera: Hesperiidae)

Weexaminedpatterns of genetic variationbetween the transcontinental speciesPyrgus communis(Grote) andPyrgus albescensPlötz (Hesperiidae) toexaminewhetherpatterns ofmolecular variation are congruentwith the taxonomy. Sequencedata frommitochondrialDNAandnuclearDNA failed to distinguish the two taxa. Although substantial genetic variation is explained by the two nominal taxa, more variation is exp...

Evolution of extreme proboscis lengths in Neotropical Hesperiidae (Lepidoptera)

Exaggerated morphologies have evolved in insects as adaptations to nectar feeding by natural selection. For example, the suctorial mouthparts of butterflies enable these insects to gain access to floral nectar concealed inside deep floral tubes. Proboscis length in Lepidoptera is known to scale with body size, but whether extreme absolute proboscis lengths of nectar feeding butterflies result f...
