The male of Idionyx carinata

One of the reasons why I went back to Huu Lien, apart from the Gomphids, was to look for the male of Idionyx carinata. I saw several females cruising in the forest and eventually there he was, the male. Always good to find that your earlier identification was correct. The male has a small yellow spot on the anteclypeus like the female and the thorax pattern is the same. The proof of the pudding is in the massive and strange appendages. What do they do with this?

Idionyx carinata, male, such a friendly little chap

That is, until he shows you his "thing" 


  1. Waouh! The anal appendages are really amazing! It should be used to open beer bottles, no?

  2. That would definitely work! Tiny beer bottles, but yes.
