The late 19th century British military men who had the leisure to turn into naturalists seemed to spend their days assigning “common names” to butterflies which had been described in the preceding centuries. As a result, the plains and hills of India are populated by exotic British nobles and their hangers on. We know these names from Charles Bingham’s monographs on the butterflies of India, but I wonder whether the idiosyncracies are his alone. The Dark Archduke (Lexias dirtea) was far from rare in the Hollongapar Gibbon Sanctuary. I kept noticing the brightly spotted females (see the featured photo) in clearings and along tracks in the jungle, as they came briefly to rest on the ground.
I had a harder time spotting the male. The one time I was certain was when I saw the specimen in the photo above. The brown spotted one is the male L. dirtea. The brightly striped one is a Common Lascar (another example of the idiosyncratic British naming system). I saw several butterflies perched just above head height on bushes around the tracks that I followed, which could be the male.
The photo that you see above is of a Popinjay (Stibochiona nicea). The archaic 19th century word describes a vain and colourfully dressed person from a middle English word for parrot, descended from Arabic through Spanish and French. This name also comes to us from Charles Bingham’s famous monographs on the butterflies of India. There were a couple of times when I was not sure that a similar looking butterfly was really the Popinjay; it could have been the male Dark Archduke. The spots at the wing edges of a Popinjay extend over both fore and hind wings, but on the male Dark Archduke similar decorations occur only on the hindwing. Information on the Popinjay is scarce; all I could find were descriptions. Nothing seems to be recorded about its caterpillars, and what they feed on, nor about its caterpillar and pupa.
The pupa that someone found on a dry leaf (photo above) was very likely to be of a Dark Archduke. I wish I’d managed to see one of its caterpillars. The photos that I saw of the later moults of the Dark Archduke’s caterpillars are spectacular.
So many archdukes and only one count! I saw this single Grey Count (Tanaecia lepidea) basking in the last light of the day. Interestingly, this is more widespread in India, being found all along the foothills of the Himalayas east of Uttarakhand, and in the Western Ghats. I may have seen this before in the nearby reserve forest of Nameri, north of the Brahmaputra, but I don’t recall seeing it in other parts of India. I did not see the caterpillars of this species, nor the pupa. Descriptions and photos of these earlier stages of its life-cycle make me believe that I’m missing something spectacular.
