A new species of Sesiidae, tribe Osminiini from Peninsular Malaysia, Heterosphecia pahangensis Skowron, displaying numerous bee-mimicking features, is described. DNA barcodes showed significant differences with related taxa. However, the paucity of Sesiidae barcodes from Southeast Asia prevents meaningful taxonomic comparisons. The closest match out of published data on Sesiidae barcodes is Het...

Road-kill represents a major threat for butterflies and more generally pollinators. Here we report an observation of conspicuous aggregations mud-puddling on roadsides and, this reason, being massively road-killed by farm vehicles. While the reported itself may not entail significant to populations observed species, it provides opportunity discuss overlooked ecological trap, potentially affecti...

When an electronic system is subjected to a sufficiently strong magnetic field that the cyclotron energy is much larger than the Fermi energy, the system enters the extreme quantum limit (EQL) and becomes susceptible to a number of instabilities. Bringing a three-dimensional electronic system deeply into the EQL can be difficult however, since it requires a small Fermi energy, large magnetic fi...
