Abstract
Danaus chrysippus (L.), one of the world's commonest butterflies, has an extensive range throughout the Old-World tropics. In Africa it is divided into four geographical subspecies which overlap and hybridise freely in the East African Rift: Here alone a male-killing (MK) endosymbiont, Spiroplasma ixodetis, has invaded, causing female-biased populations to predominate. In ssp. chrysippus, inside the Rift only, an autosome carrying a colour locus has fused with the W chromosome to create a neo-W chromosome. A total of 40-100% of Rift females are neo-W and carry Spiroplasma, thus transmitting a linked, matrilineal neo-W, MK complex. As neo-W females have no sons, half the mother's genes are lost in each generation. Paradoxically, although neo-W females have no close male relatives and are thereby forced to outbreed, MK restricts gene flow between subspecies and may thus promote speciation. The neo-W chromosome originated in the Nairobi region around 2.2 k years ago and subsequently spread throughout the Rift contact zone in some 26 k generations, possibly assisted by not having any competing brothers. Our work on the neo-W chromosome, the spread of Spiroplasma and possible speciation is ongoing.

Hu P, Wang R. The complete mitochondrial genome of Parantica sita sita (Lepidoptera: Nymphalidae: Danainae) revealing substantial genetic divergence from its sibling subspecies P. s. niphonica. Gene 2018; 686:76-84.

Abstract
Currently, there are two subspecies of the chestnut tiger butterfly (Parantica sita) recognized in China. P. s. sita is widely distributed in southwest China and P. s. niphonica in Taiwan. Periodically, Taiwan Island and the Chinese mainland have been connected and separated because of sea level changes caused by Pleistocene glaciations, most likely influencing the genetic structure among P. sita populations on both sides of the Taiwan Strait. Also, P. s. niphonica's well-documented long-distance migration may have influenced genetic differentiation within this species as well. So, investigation of the genetic differentiation of these two subspecies is well warranted. In this study, we sequenced the complete mitogenome (15,156 bp in length) of P. s. sita and its general characteristics agreed with general butterfly mitogenomic characteristics. However, when compared genetically with P. s. niphonica, P. s. sita diverged substantially. First, there were 4.1% variable sites between these two subspecies, with 5.3% at COI and 3.8% at COII, differences much greater than those expected of general interspecific divergences in butterflies. Second, there was a 59 bp fragment deletion in the A + T rich region of P. s. sita and, third, the relationships of these two subspecies and P. luzonensis could not be distinguished using Bayesian inference and P. s. niphonica first clustered with P. luzonensis, rather than P. s. sita, using maximum likelihood. Based on these results, we propose that P. s. sita and P. s. niphonica are independent species instead of subspecies. This proposal should be clarified through further research.

Abstract
Populations of widespread pest insects in tropical areas are characterized by a complex evolutionary history, with overlapping natural and human-mediated dispersal events, sudden expansions, and bottlenecks. Here, we provide biogeographic reconstructions for two widespread pest species in the tiger moth genus Creatonotos (Lepidoptera: Erebidae: Arctiinae) based on the mitochondrial cytochrome c oxidase subunit I (COI) gene. The Asian Creatonotos transiens reveals shallow genetic divergence between distant populations that does not support its current intraspecific systematics with several local subspecies. In contrast, the more widespread Creatonotos gangis comprises at least three divergent subclades corresponding to certain geographic areas, i.e. Australia, Arabia + South Asia and Southeast Asia. With respect to our approximate Bayesian computation (ABC) model, the expansion of Creatonotos gangis into Australia is placed in the Late Pleistocene (~65–63 ka). This dating coincide with an approximate time of the earliest human migration into the continent (~65–54 ka) and the period of intervisibility between Timor and Australia (~65–62 ka). Our findings highlight that the drying Sunda and Sahul shelf areas likely support successful migrations of Asian taxa into Australia during the Pleistocene. The phylogeographic patterns discovered in this study can be used to improve the effectiveness of integrated pest control programs that is a task of substantial practical importance to a broad range of agricultural stakeholders.

Abstract
Butterflies of the genus Danaus are known to sequester toxic cardenolides from milkweed host plants (Apocynaceae). In particular, Danaus plexippus efficiently sequesters and stores these compounds, whereas D. chrysippus, is considered to poorly sequester cardenolides. To estimate its sequestration capability compared with that of D. plexippus, larvae of both species were jointly reared on Asclepias curassavica and the major cardenolides of the host plant, calotropin and calactin, were analyzed in adults sampled at different time intervals after eclosion. Both cardenolides were detected in body and wings of D. plexippus. Whereas the calotropin-concentration remained constant over a period of 24 days, that of calactin steadily decreased. In the body, but not in the wings of D. chrysippus, calactin only was detected in low amounts, which was then almost completely lost during the following 8 days after eclosion, suggesting that in contrast to D. plexippus, cardenolides seem to be less important for that butterfly's defence against predators.
