Here are some pictures from common butterflies mating in South-East Asia. Enjoy ! 1a and 1b. Atrophaneura varuna zaleucus (Hewitson,[1865]), in copula. Kuang Si (Luang Prabang), Laos, July, 19, 2019. The male is not very visible but is present under the female; density of vegetation prohibited a closer photo! 2. Graphium agamemnon agamemnon (Linnaeus,1758), in copula. Kuang Si (Luang Prabang), Laos, July, 19, 2019. 3. Leptosia nina nina (Fabricius, 1793), in copula. Pak Beng (Oudomxai), Laos, July, 17, 2019 4. Tanaecia julii bougainvillei (Corbet, 1941), in copula. Ko Ngai (Krabi, Thailand), July, 29, 2019 5. Papilio polytes romulus Cramer, [1775], ♂ and ♀, male chasing a female. Ko Ngai (Krabi, Thailand), 31 juillet 2019 (poor photo !) 6, 7 and 8. Papilio memnon agenor Linnaeus,1758, ♂ and ♀, f. distantianus Rothschild,1895, male chasing a female. Ko Ngai (Krabi, Thaïlande), August 1st, 2019

Your Tanaecia julii from Krabi should be ssp. xiphiones. Ssp.bougainvillei is a synonym to mansori which occurs only in Satun-Thailand and west Malaysia.

"Your Tanaecia julii from Krabi should be ssp. xiphiones. Ssp. bougainvillei is a synonym to mansori which occurs only in Satun-Thailand and west Malaysia" Thank you ! Is this a female Tanaecia julii xiphiones? In my documentation (Ek-Amnuay, Yutaka), I do not see any butterfly presenting these blue marks on the hind wings. Or would it be an aberrant male?

Very interesting specimen, I’ve never seen one like it. I asked Yutaka and he suggested that it could be mosaic gynandromorph or aberration of T.julii.

A second picture of the same sample Tanaecia julii xiphiones. The species was very abundant inside the forest last July (but only seen around small pathes in the forest, not at all in open areas, like hotels gardens, or on the seashore).

T.julii is a forest species and like some other species of Cynitia and Euthalia genus they like to fly along small forest paths and rest on vegetation and males often rest on the ground perhaps looking for some minerals. Once disturb they can be easily approach again few meters ahead and when they reach their territory boundary they will fly back along the path. They rarely would fly deep into the forest, unless threaten. Tanaecia julii can be common in the right season.
