The first week of April had nice spring days to look for butterflies at Mount Ba Vi - located 70 km west of Hanoi, a large part is classified as national park.
The survey was mainly conducted in degraded forest at the foothills, in better quality forest at around 500-600m asl. Ca. 75 species were recorded, most of them wide-ranging, common species with broad habitat tolerance. Among them a few new species for me.
Highlights: Byasa cf. dasarada (few individuals around Bauhinia flowers, spotted with binoculars), Papilio dialis doddsi, Suada albolineata.
Ba Vi is an amazing place and I know that there are loads of interesting species waiting to be found.

Papilio polytes, 3th or 4th instar caterpillar, with the osmeterium everted behind its head
This Y-shaped eversible gland, located mid-dorsally behind the head, is a defensive organ found in all papilionid larvae, in all stages

Appias lalage, male - a new species for me
Appias albina, male
Argyreus hyperbius, male
Tirumala cf. septentrionis larvae
Caterpillars in Danainae subfamily have 2 or more long dorsal filaments. They are usually banded with bright warning colour usually black, yellow and white
Cupha erymanthis
Faunis eumeus sipping juice from rotten fig
Lethe confusa
This male shows very strong territory habit. Whenever any butterfly fly into its territory, it chases away them aggressively

Neope muirheadii
Mycalesis mucianus
Melanitis phedima
Zemeros flegyas - very common all year round, but not often seen with wings fully spread
Yasoda tripunctata
Yasoda tripunctata, showing the distinctive pattern of its upperwings
Cigaritis syama
Heliophorus delacouri, male

Syntarucus plinius
Suada albolineata - a species described in 2000 from northern Vietnam
Halpe sp.
Pelopidas conjuncta, copula
Ancistroides nigrita
The proboscis is particularly long compared to other skipper species
This is a small moth but it looks like a butterfly, because it not only fly in the day but it also settle with its wing held vertically. But look at antennae, they are not clubbed - a main characteristics of moths.

Saraca dives, one of North Vietnam's most beautiful flowering trees,
features in spring nectar-rich blossom that attract many butterflies
It's also the time for the first wave of Speckled Black Cicadas Gaeana maculata

The proboscis is particularly long compared to other skipper species
Many skippers are brown, unmarked and not typical of what enthusiasts, hobbyists and nature photographers would find particularly beautiful in a butterfly. Hence it is not surprising that many of these ubiquitous butterflies go about their daily lives, flitting amongst flowers in the early morning hours and later hours of the day largely unnoticed.
