Ahropala identification and behaviour

[DaveChiangMai]

Images from Doi Inthanon, north Thailand, this week.

Image 1, please can I have some help on the identification as I do not have other images resembling this one. Evergreen forest at 1,100 metres.

Images 2 and 3, taken in lower Dipterocarp forest at about 500 metres. These I take to be Arhopala atrax. Does anyone know what behavior this is. There were at least 50 of them, all gathered on the same leaf. They were not feeding, nor appearing to be involved in any mating behavior. Communal roosting? (Although this was mid afternoon).

Many thanks

1st is Arhopala bazalus teesta

2nd is probably Arhopala asinarus. I'm not certain because i don't have my references with me atm. That is some interesting behaviour; i never knew lycaenids would congregate like that

Many thanks.
Yes, I also never have seen this behavior.
And yes, of course, I suddenly realize second one cannot be atrax as no tail.

2nd is Arhopala asopia.
The markings are narrower & lighter, & the FW less pointy.
