This study has the objective of describing hilltopping and territorial behavior adult males bivoltine butterfly Actinote zikani during six flying seasons (2016-2019). Males used same areas these territories presented patterns horizontal vertical stratifications all seasons. The amount solar radiation on black wings A. seems to contribute rapid warming this butterfly, that together with protecti...

The morphological characters of Cirrochroa aoris (Large Yeoman) and C. tyche (Common Yeoman) are very similar making identification confusing and difficult. The genomic DNA of the two species was subjected to RAPD-PCR analysis with six decamer oligonucleotides, i.e. MA5, MA6, MA8, OPB12, OPT4 and OPT5. All of them produced discrete bands of various lengths revealing genetic variations as well a...

Signa are sclerotized structures located on the inner wall of the corpus bursa of female Lepidoptera whose main function is tearing open spermatophores. The sexually antagonistic coevolution (SAC) hypothesis proposes that the thickness of spermatophore envelopes has driven the evolution of the females signa; this idea is based in the fact that in many lepidopterans female sexual receptivity is ...

Habitat loss and climate change are rapidly converting natural habitats and thereby increasing the significance of dispersal capacity for vulnerable species. Flight is necessary for dispersal in many insects, and differences in dispersal capacity may reflect dissimilarities in flight muscle aerobic capacity. In a large metapopulation of the Glanville fritillary butterfly in the Åland Islands in...
