Endosymbiosis morphological reorganization during metamorphosis diverges in weevils
Communicative & Integrative Biology, 2020 Virtually all animals associate with beneficial symbiotic bacteria. Whether and how these associations are modulated across a host’s lifecycle is an important question in disentangling animal-bacteria interactions. We recently reported a case of complete

Insect Conservation and Diversity, EarlyView.We surveyed 119 stands of common milkweed (Asclepias syriaca) across an urbanisation gradient to investigate how restored garden habitat might ameliorate the negative effects of urbanisation on specialist herbivores. Surprisingly, we found most herbivores (including the monarch butterfly) had greater occupancy on common milkweed towards an urban centre.

Insect Molecular Biology, EarlyView.Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Orientation-dependent photonic bandgaps in gold-dust weevil scales and their titania bioreplicates
Beilstein Journal of NanotechnologyThe scales of the gold-dust weevil Hypomeces squamosus are green because of three-dimensional diamond-type chitin–air photonic crystals with an average periodicity of about 430 nm and a chitin fill fraction of about 0.44.
