The function of appendage patterning genes in mandible development of the sexually dimorphic stag beetle. Developmental Biology , 2017; 422 (1): 24 DOI: 10.1016/j.ydbio.2016.12.011 Cite This Page : ...

Unfortunately, there’s a tradeoff. Researchers in Japan discovered that beetles with longer mandible weapons have smaller testicles and less ejaculate than their brethren. In a paper published ...

Mouthparts can be highly modified, as in the straw-like maxillae of butterflies, or exceptionally enlarged, as in the mandibles of stag beetles that are used for fighting rather than feeding. However, ...

They found diminished mandible size when expression of the peptide was suppressed, and that it was specifically expressed in the "fat body", where beetles store nutrients. This has important ...

This is a characteristic of many predatory beetles. A darkling beetle's mandible is usually hidden. Hall said ground beetles sometimes have larger eyes because they are hunters. They also are ...

Importantly, this exquisitely preserved beetle (Cretoparacucujus cycadophilus) exhibits physical characteristics consistent with pollination, namely mandibular cavities, which it likely used to ...

Collaborative Japan-US research coordinated by Nagoya University has now shed light on the genetic control of stag beetle mandible development. The study was published in Developmental Biology.
