The distinctive outline of Mount Ba Vi, seen from Dông Mô Lake. This mountain has three peaks: the highest is Dinh Vua at 1,296m, followed by Tan Vien at 1,226m and Ngoc Hoa at 1,120m
Last year, I conduct regular surveys at Ba Vi National Park (located 70 km west of Hanoi). Regular sampling was carried out from March to November 2017. The surveys were performed along a ca.5km transect (ranging in altitude from 100-800m) divided in different segments, along paths and small roads. A total of 15 man-days were spent in the field.
Three types of ecosystem were surveyed i. e. secondary forest, old-growth forest with dense canopies and ecotones dominated by shrubs. The old-growth, closed-canopy evergreen forest, from 700-800m to 1,300m asl, has been under-surveyed for some reasons, hence the lack of strictly montane species in my checklist. I will try to fill that gap this year.
Close to the summit: Dinh Vua Peak (1,296m asl) on the left, Tan Vien Peak (1,226m asl) on the right.
The natural old-growth forest is mainly distributed at elevation above 700m

To identify the species, specimens encountered were either observed with binoculars or photographed. Few specimens were captured and none were collected for later identification (permit is required for collecting in nature reserves and national parks). I am fully aware of the limitation of this sampling method ("butterfly-watcher" style...), especially for taxonomically complicated genera (in the Hesperiidae family notably) which require sometimes that specimens are collected for further examination. Nevertheless, 95% of the specimens photographed/captured were confidently identified at species-level (the remaining at genus-level).
In total, I recorded c.180 species of butterflies. I am aware of two previous studies of Ba Vi's butterfly fauna. The one of Bui Xuan Phuong et al. (2003) listed 141 species, the one of Vu Van Lien et al. (2013) 92 species.
Intense studies in this area will certainly reveal much more species, especially members of the Hesperiidae and Lycaenidae families which have low detectability because of their small size, localized appearance and strong habitat preferences.

Troides species are usually seen gliding slowly over the canopy and not often seen feeding off the flowers at eye-level, moving from bush to bush. An opportunity not to be missed!
Byasa dasarada barata, female
Papilio paris belongs to the subgenus Achillides ("Gloss Papilios"). The other representants of this subgenus known in Vietnam are P. doddsi, P. arcturus arcturus, P. krishna charlesi & P. bianor gladiator.
This form is a mimic of the unpalatable (toxic) Atrophaneura swallowtails, while form agenor is non-mimetic
This puddling congregation was one of the rare I spotted during this survey
Quite unusual to see this species flowering - more often seen puddling
Both sexes exhibit a flight pattern similar to the Danainae models which they mimic, slow and seemingly unafraid; but, unlike the models, will fly away quickly if disturbed.
The forewing has a triangular hyaline (glass-like) patch with black borders
Looks superficially like D. pasithoe but larger and UnH yellow postdiscal markings arranged differently and more regularly
There may be as many as 34 species of Pieris worldwide, although the status of some is uncertain. The commonest and most widespread species is rapae, which was originally restricted to Europe and temperate Asia but has been introduced accidentally to North America, Africa, South-East Asia, Australia and New Zealand.
The caterpillar of this species is seen as a pest for agriculture.
An addition to the species list from Spring 2018
Beneath, the wings show many rather faint and short transverse striae, giving a "mottled" appearance
Ixias pyrene - same remark than Hebomoia glaucippe
Leptosia nina - a low flying (usually less than 1 meter high) and delicate Pierid butterfly with weak and erratic flight
The genus Leptosia comprises 9 species, all found in Africa, except for L. lignea which is endemic to Sulawesi and L. nina which ranges from India to Australia.

According to Monastyrskii & Devyatkin (2016), the subfamily Amathusiinae is represented in Vietnam by 10 genera: Faunis (5 species), Aemona (7 species), Stichophtalma (8 species), Amathusia (1 species), Amathuxidia (1 species), Zeuxidia (2 species), Thaumantis (1 species), Thauria (1 species), Discophora (4 species), Enispe (3 species).
Stichophthalma howqua suffusa has been raised to species S. suffusa Leech, 1892 (Monastyrskii & Devyatkin, 2008). S. suffusa tonkiniana has an ocre-yellow ground color on the Up of both wings with completely fused submarginal black markings on the UpH.
At Ba Vi, this species occupies both primary and secondary forest habitats, at all elevations.
Thauria lathyi feeding on rotten fruits with Stichophthalma suffusa tonkiniana
Thaumantis diores
Faunis eumeus enjoying the glorious morning sun
The genus Thaumantis ("Jungle Glories") comprises 5 species (diores, klugius, noureddin, odana, hainana). Only T. diores is known from Vietnam, with two subspecies recognized : T. diores diores in the north and T. diores splendens further south.
Thaumantis diores is a common sight in my habitual butt hunting grounds around Hanoi, both in lowland and montane forests. This species inhabits shady undergrowth and is attracted by fruits and moist litter.
According to Monastyrskii & Devyatkin (2016), 5 Faunis species have been recorded in Vietnam viz. F. eumeus (N. and C. Vietnam), F. canens (N. and C.), F. excelsa (N. and C.), F. bicoloratus (C.) and F. centrala (C.).
Centrala and excelsa have Up of both wings grey. The 3 other species have brown Up.
Four Danaus species are recorded in Vietnam: D. chrysippus, P. genutia, D. melanippus & D. affinis. Only the two former are recorded in the North of the country, where they are very common.
The caterpillars of the sub-family Danainae have several long paired 'tentacles' (stinkhorns) on the back
The genus Parantica comprises 39 species, of which 6 are known to occur in Vietnam viz. aglea, agleoides, aspasia, melaneus, swinhoei, sita.
E. sylvester is one of my favourites, with the dark metallic blue sheen (upperwing) contrasting with the row of pale blue submarginal spots
 |  |
To my knowledge, until now, there was only one record from northern Vietnam (Cuc Phuong). But as this species is also known from southern China, its presence at Ba Vi is not really surprising.
Monastyrskii & Devyatkin (2016) listed 3 Tirumala species from Vietnam - septentrionis, limniace and gautama, the former two widespread throughout the country, the latter recorded from the center (Quang Binh Prov.) and south. Tirumala limniace is similar to T. septentrionalis, but with broader and paler blue streaks as well as spots. T. gautama can be easily separated from the latter two by the FW discal cell with an additional blue streak along the anterior margin
The smell of the handlebar grip of my motorbike was irresistible to this individual
The wet season form is characterized by large submarginal eyespots. These patterns are conspicuous when the butterflies are at rest on leaf litter or low herbage.
The dry season form lacks conspicuous wing markings. Such changes may favour crypsis and the absence of conspicuous pattern elements in the dry season when the satyrine butterflies rest inactively on the dead leaves while the wet season butterflies, which are active and rest intermittently on the green herbage, may use eyespots and bands as active anti-predator devices
Mycalesis individual of the mineus-group, very likely M. perseoides
Less elusive than other Lethe butterflies - often witnessed males perched at eye-level defending their territory and chasing away any 'intruders' (of whatever species)
Northern Vietnam is a region of particularly high levels of diversity for this genus, hosting over 80% of the known number of species (Monastyskii pp.32. in Anon, 2001).
An addition to the species list from Summer 2018
25 Ypthima species are known to occur in Vietnam (Monastyrskii & Devyatkin, 2016)
This rather elusive butterfly has its hindwing sharphly angled at tornus. The undersides are of a drab ochreous brown with heavy but blurred striation, giving it a cryptic appearance among the leaf litters of the undergrowth
Discophora species currently known in Vietnam: sondaica, deo, timora and aestheta - the last one described in 2003 from S.Vietnam (Dong Nai Prov., Cat Tien National Park).
One of the most widespread of all butterflies, found on every continent except Antarctica (where no butterflies occur). Despite its incredible range, V. cardui is monotypic, i.e. there are not recognized subspecies. This probably reflects the fact that it is strongly migratory, a behavior that acts to inhibit localized population differentiation.
This is a colony-forming species, and it's unusual to see only one specimen
The flight is weak and fluttery, but persistent. In cloudy weather they roost openly on stems or grass-heads.
Recently, some revisions on the Asian continental Kallima have been carried out by Nakamura & Wakahara (2013) and Nakamura (2014). Monastyrskii & Devyatkin (2016) listed 3 species of Kallima in Vietnam: K. albofasciata continentalis (in the South), K. incognita and K. alicia kishii (the two latter widely distributed throughout the country)
It's often difficult to get close enough to a butterfly to get a photo, but from time to time they come to you!
The eyes of both sexes are yellow but those of the female are darker with varying degrees of brown shading.
This species mimics Danaids especially Parantica sita and P. melaeneus, but differs in having submarginal lunules on both wings.
There are about 14 species in the genus Symbrenthia, of which 4 are found in Vietnam - lilaea, hypselis, niphanda, leoparda. The former two are recorded in the north and center of the country, the latter two only from the north. S. lilaea and S. hypselis are the commonest members of the genus in Vietnam - but the latter have narrower habitat requirements and is much less often encountered.
Distinctive flight with its wings flapping stiffly between the horizontal position and a few degrees below the horizontal
According to Monastyrskii & Devyatkin (2016), 5 Pantoporia species have been recorded in Vietnam: P. hordonia, P. sandaka, P. paraka, P. aurelia & P. bieti. The first three are widespread, the fourth is known from the Center and South, and the latter is only recorded from the North-West corner of the country (Lao Cai)
The Charaxinae are a group of large, robust Nymphalids characterised by their rapid and powerful flight, falcate apexes, and a habit of feeding at dung and carrion. They are represented in Africa by Charaxes, Euxanthe and Palla; in the neotropics by Consul, Memphis, Prepona and Agrias; and in the Oriental and Australian regions by Polyura and Charaxes.
Monastyrskii & Devyatkin (2016) listed 6 Charaxes species in Vietnam viz. solon, bernardus, marmax, aristogiton, kahruba & harmodius.
Eulaceura osteria
An interesting characteristic of this butterfly is that when disturbed, it flies rapidly and zips to the underside of a nearby leaf where it settles with its wings closed

E. monina kesava is recorded in the north and the center of the country. It is replaced further south by E. monina remias. This species is one of the commonest members of the genus in Vietnam.
Formely known as Euthalia niepelti Strand, 1916
Monastyrskii & Devyatkin (2016) didn't listed this species from northern Vietnam. But its presence here is not surprising, as it's also known from southern China
Note the circular bulge on the hindwing, indicating the presence of the circular brand on the upperside
 |  |
Two species of Tongeia are known from Vietnam (Monastyrskii & Devyatkin, 2016): T. potanini (subsp. potanini in the North, subsp. umbriel in Central VN) and T. ion (North only)
This species is widespread (from India to Malaysia and north to Japan) but it appears to be very local in occurrence. In Vietnam, it is only recorded from Ha Giang Prov. (North) and Lam Dong Prov. (Centre) (Monastyrskii & Devyatkin, 2016)
This species is unique in that it features green undersides, and can camouflage itself very well amongst green foliage. Its English name is "Green Flash".
Neopithecops zalmora
A widespread species but the paucity of records in Vietnam suggest it is very local in occurrence
In North Vietnam, Monastyrskii & Devyatkin (2016) only mentioned it from Ba Be N.P.; I also found a mention of its occurrence at Tam Dao by Vu Van Lien (2013)
In Vietnam, this species appears to be very local in occurrence. It's only recorded from Ha Giang and Lang Son Prov. (North V.) and Quang Binh Prov. (Central V.) (Monastyrskii & Devyatkin, 2016)
Monastyrskii & Devyatkin (2016) listed 2 Satarupa species in Vietnam viz. gopala & zulla - the former widespread (N., C.), the latter only recorded from Lao Cai Prov..
 |  |
The genus Tagiades comprises 17 known species. According to Monastyrskii & Devyatkin (2016), 7 have been recorded in Vietnam: japetus, gana, hybridus, parra, litigiosa, menaka & cohaerens.
Menaka, litigiosa, parra, hybridus and cohaerens show in both sexes large white tornal area of HW reaching space 4, unlike japetus and gana.
Quite common in lowland forests as well as semicleared partly cultivated areas around villages
Whilst identification of Halpe species is problematic to say the least, this would appear to be either H. zema or H. zola. Genus Halpe needs specimens and checking genitalia.
In Vietnam, zema is only recorded from Tuyen Quang Prov. (North) whilst zola is more widespread (N. & C. of the country)
Unmistakable with its long narrow forewing
M. druna can be easily confused with M. aria, but the male of the former has a large & curved grey brand whereas it is narrow in aria
Matapa sasivarna - Note the extensive metallic green hair scales on body
Note the UnH spots in spaces 2-5 neatly in line (straight line of decreasing spots upwards), distinctly white, no spot 6, UpF with two cellspots
Parnara bada & apostata have no FW cell spots. Male
P. ganga usually have a single lower FW cellspot. P. guttata usually have two
Parnara sp.
Parnara species show a great similarity of the external features and it is often impossible to
determine with certainty the species only from a photograph. For proper
identification, it is better to voucher the specimen to have a complete
view of the FW and HW pattern (often incomplete in a shot) and, ideally,
to confirm the ID by examination of the genitalia - a matter for specialists.
In the females, the size and spotting pattern are highly variable, this making most of the species almost indistinguishable by the external features.
In the females, the size and spotting pattern are highly variable, this making most of the species almost indistinguishable by the external features.
Species described in 2000. I observed it at Tam Dao & Ba Vi National Parks, and Huu Lien Nature Reserve
This is a large skipper, FW spots large & yellowish, HW spots whitish
Another difficult genus. Identification by the wing patterns is not easy. After taking a photograph in the wild, it is useful to catch the specimen and to inspect genitalia
Sometimes positive identification of Hesperiidae is not possible until genitalia (especially of males) have been carefully dissected and examined in detail; this is especially true for species belonging to difficult genera such as Telicota
This genus is represented in Vietnam by 7 species – colon, augias, linna, besta, bambusae, ancilla and ohara (Monastyrskii & Devyatkin, 2016)
Some day-flying moths encountered during the surveys:
 |  |
 |  |
The species in this genus mimic butterflies of the agehana-group in the Papilio genus and Atrophaneura species. This is not a day-flying moth; adults fly in the evening and at night - flight activity starting just after sunset - and are attracted by light
Chalcosiinae Zygaenid, Cyclosia cf. papilionaris. This moth, which is a female, mimics the Glassy Tiger Parantica aglea in appearance and flight. Sexually dimorphic, the male is chocolate brown
Chalcosiinae, Zygaenidae Amesia aliris
Chalcosiinae Zygaenid, Pidorus atratus or glaucopis
Agaristinae Noctuid, Episteme adulatrix - colourful and attractive like a butterfly!
Agaristinae Noctuid, also something in the genus Episteme I think
Callidula sp.
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.

Sphingidae, Macroglossinae, "Hummingbird Moth", possibly Cephonodes hylas
