RESUMO

Global change influences species' seasonal occurrence, or phenology. In cold-adapted insects, the activity is expected to start earlier with a warming climate, but contradictory evidence exists, and the reactions may be linked to species-specific traits. Using data from the GBIF database, we selected 105 single-brooded Holarctic butterflies inhabiting broad latitudinal ranges. We regressed patterns of an adult flight against latitudes of the records, controlling for altitude and year effects. Species with delayed flight periods towards the high latitudes, or stable flight periods across latitudes, prevailed over those that advanced their flight towards the high latitudes. The responses corresponded with the species' seasonality (flight of early season species was delayed and flight of summer species was advanced at high latitudes) and oceanic vs. continental climatic niches (delays in oceanic, stability in continental species). Future restructuring of butterfly seasonal patterns in high latitudes will reflect climatic niches, and hence the evolutionary history of participating species.

RESUMO

The tussock moth genus Daplasa Moore, 1879 is reviewed from China. Hitherto four species are recognized, where one new species, D. nivisala sp. n., is described and one new combination D. melanoma (Collenette, 1938) comb. n. is proposed. Adults and their genital structures are provided, together with a key to the species of Daplasa with the occurrence in China.

RESUMO

We examined the global phylogeography of gypsy moth (Lymantria dispar L.) using molecular data based on mitochondrial and nuclear genes. Populations from all biogeographic regions of the native and introduced range of L. dispar, were sampled to fully document intraspecific and subspecies variation, identify potential cryptic species, and to clarify the relationships among major phylogeographic lineages. We recovered three major mtDNA lineages of L. dispar: Transcaucasia; East Asia + Japan; and Europe + Central Asia. The circumscription of these lineages is only partially consistent with the current taxonomic concept (i.e., L. dispar dispar; L. dispar asiatica; L. dispar japonica), with the following important discrepancies: (1) north-central Asian populations, including topotypical populations of L. dispar asiatica, may be more closely related to European rather than Asian segregates, which would require the synonymization of the taxon asiatica and establishment of a new name; (2) the Japanese populations (L. d. japonica) are not distinct from east Asian populations; (3) the presence of a distinct, unnamed mitogenomic lineage endemic to the Trancaucasus region. We demonstrated that the population from Transcaucasia contains the highest mitochondrial haplotype diversity among L. dispar, potentially indicative of an ancestral area for the entire dispar-group. Our study corroborates the endemic Hokkaido, Japan taxon Lymantria umbrosa (Butler) as the sister group to all other L. dispar populations, but the applicability of the names umbrosa versus hokkaidoensis Goldschmidt needs to be re-evaluated. The ancestral area analysis suggest that Japan was likely colonized via Sakhalin ∼1 Mya, in contrast to previous studies which have suggested colonization of the Japanese archipelago via the Korean Peninsula. Lastly, mitogenomic variation within L. dispar is incongruent with phylogenies based on nuclear DNA, as nDNA gene phylogenies did not recover the three major mtDNA lineages, and also failed to recover L. dispar and L. umbrosa as reciprocally monophyletic.

RESUMO

Ultraviolet patterns in butterflies have been recognized and studied for many years. They are frequently involved in both intraspecific and interspecific interactions. Only a handful of studies, however, have investigated possible links between ultraviolet (UV) reflectance and ecological properties in some genera of the Lepidoptera as a whole. This study examines the impact of habitat and distribution on UV reflectance patterns on the wings of 106 species and subspecies of Colias butterflies. Based on standardized digital photographs, we performed a multivariate analysis of relations between UV reflectance, preferred habitat (alpine, arctic, dry grasslands, humid, forest, and ubiquitous), and distribution area (Afrotropical, Nearctic, Neotropical, European, Caucaso-Anatolian, boreal Eurasian, Central Asian mountains, northern China and Japan, and northern Oriental region). UV patterns occur more frequently in the male (60 taxa) than in female (25 taxa) Coliads. This difference in presence of UV patterns is used for differentiating between the males and females of a given species or subspecies. Further possible explanations of this phenomenon are also discussed. This study also shows that particular configurations of UV patterns are significantly associated with particular distribution areas. This relation is relatively strong but overall trends remain unclear. Based on the results of this study, it can be concluded that there exists a significant difference in the configuration of UV reflectance between the sexes, and that the configuration of UV reflectance significantly interacts with the geographical distribution of Colias species and subspecies.
