Hi Soowon


I have a specimen of Lamprima aurata Latreille 1817 (Coleoptera:
Lucanidae) which possesses three fully developed legs on location of the
left hind leg. I believe it got damaged in larval or pupal stage.


Best regards

Dear James, Ken, and others


Thank you for your information on extra-limb mutant insect. I am trying
to contact the first author of the paper Ken suggested but successful


Yes, the picture sent from James is a similar one I found from a
plecopteran adult.


What I am curious about is how or why it happened
morphologically/genetically. Unfortunately I have little access to any
good source of papers or experts on this issue, mainly due to my lack of
knowledge in this area and in part limited accessibility to research


In particular, I found very interesting that this three-leg mutation on
where it should be one hind leg shows one short, one medium, and one
long leg as if the three are mimicking fore-, mid-, and hind-legs.


Hopefully someone can lead me to an expert on this so that I can learn
more about it.
