It's aberrant, maybe a problem in the pupa. |

hi alexandru it's very likely of traumatic origin; the leg was lost during one of the larval instars (probably not the last one) and only partially regenerated i don't think it results from an injury suffered by the pupa, in such cases the insect almost never does survive |

When there are problems with the pupa, usually there are two possible results: 1 - it dies 2 - it survives but the damaged leg is truncated or missing in the adult It happened several times when I found pupae during my entomological travels and put them in vials to get adults. Usually some of them die or have these problems caused by wounds sustained from shaking during transport by car. |

Thanks Maurizio This isn't the first abberant scarab beetle from my collection, I have a female of Potosia cuprea which has the apical part of mesosternum bilobate
