Abstract The Japanese rhinoceros beetle Trypoxylus dichotomus is a giant beetle with
distinctive exaggerated horns present on the head and prothoracic regions of the male. T …

Beetles are the largest insect order and one of the most successful animal groups in terms of
number of species. The Japanese rhinoceros beetle Trypoxylus dichotomus (Coleoptera …

Highlights•A high-quality T. dichotomus (Coleoptera, Scarabaeidae, Dynastini) genome has
been assembled.•RNAi screening using RNA-seq analysis has revealed several genes …

The draft whole-genome sequence of the Japanese rhinoceros beetle, Trypoxylus
dichotomus was obtained using long-read PacBio sequence technology. The final …

Background How novel traits integrate within ancient trait complexes without compromising
ancestral functions is a foundational challenge in evo-devo. The insect head represents an …

Male‐specific exaggerated horns are an evolutionary novelty and have diverged rapidly via
intrasexual selection. Here, we investigated the function of the conserved sex‐determination …

Many scarab beetles have sexually dimorphic exaggerated horns that are an evolutionary
novelty. Since the shape, number, size, and location of horns are highly diverged within …

As the predominant pest of alfalfa, Odontothrips loti Haliday causes great damages over the
major alfalfa-growing regions of China. The characteristics of strong mobility and fecundity …

Beetle horns are attractive models for studying the evolution of novel traits, as they display
diverse shapes, sizes, and numbers among closely related species within the family …

The flour beetle Tribolium freemani is a sibling species of the model organism and important
pest Tribolium castaneum. The two species are so closely related that they can produce …
