Subject: Archduke Caterpillar from West Sumatra… Lexias pardalis ? Lexias dirtea ?
Location: West Sumatra – Indonesia

I’m leaving in the forest in West Sumatra and i took this picture the last year. I suppose that it’s a Lexias pardalis or dirtea…. But the blue color is much more pronounced than in other pictures I found and that are usually taken in Thailand or Borneo. Is there somebody to confirm the identification of this Archduke Caterpillar ?
Thanks a lot for your help.

Your images are gorgeous and so is this Archduke Caterpillar, but alas, we haven’t the necessary skills to distinguish which member of the genus you encountered. Perhaps one of our more qualified readers like Keith Wolfe can supply some information.

Greetings Nad and Daniel,
With four species of Lexias reported for the island of Sumatra, three of whose caterpillars are known, this is most likely L. dirtea or L. pardalis (https://www.facebook.com/groups/390324371076210/permalink/706691412772836/). The blue color can be attributable to several reasons — camera settings, ambient lighting, larval maturity, or it actually being the fourth taxon, L. cyanipardus; however, here is a very similar bluish dirtea/pardalis cat from Thailand . . .
