Number: 134
Family: Pieriidae
Sub-Family: Pieriinae
Species: Prioneris philonome clemanthe (Doubleday, 1846)
Common name(s): The Red-spotted Sawtooth

The genus Prioneris comprises 6 species, all occuring in the Oriental region. Two are recorded in Vietnam - thestylis and philonome. Both are common species throughout the country.

Prioneris philonome is quite similar to Prioneris thestylis but UnH has a small orange-red basal spot and 4/5 of UnH is yellow in male.

 Male Prioneris philonome - yellow is more extensive in female (Tam Dao, June 2016)

Sub-Family: Pieriinae
Species: Prioneris thestylis thestylis (Doubleday, 1842)
Common name(s): The Spotted Sawtooth

Male bears serrate edge at the upper margins of FW where its common name comes from.  UnH of female is much yellow than in the male. All individuals photographed below are males.

The genus Prioneris comprises 6 species, all occuring in the Oriental region. Two are recorded in Vietnam - thestylis and philonome. Both are common species throughout the country. They are found in forested areas, often puddling with other Pierids and Papilionids.

Butterflies are often attracted by my sweaty clothes – and here, in Vietnam, you sweat A LOT – but also by my motorbike – an unresolved mystery!

Species: Cyrestis thyodamas thyodamas Doyère, [1840]
Common name(s): The Common Map
Photography location: Cuc Phuong N.P. (Ninh Binh Prov.)

The genus Cyrestis (“Maps”) comprises around 25 species, all except one (C. camillus/African Map) from Oriental Region. According to Monastyrskii & Devyatkin (2016), 4 Cyrestis species are currently known in Vietnam viz. themire, cocles, thyodamas and nivea

128. Chilasa clytia (The Common Mime)

Number: 128
Family: Papilioniidae
Sub-Family: Papilioniinae
Species:  Chilasa clytia Linnaeus, 1758
Common name(s): The Common Mime
Photography location: Tam Dao foothills (Vinh Phuc Prov.)

Monastyrskii & Devyatkin (2016) listed 6 Chilasa species in Vietnam viz. agestor, epycides, slateri, clytia, paradoxa and imitata - the last one described in 2003 from central Vietnam. C. clytia is certainly the commonest Chilasa species in Vietnam. It can be encountered in different types of open or semi-open habitats, even agroecosystems, whereas the other Chilasa have more more specific habitat requirements. 

Chilasa clytia caterpillars feeds on Litsea glutinosa, a common tree in secondary growth, and probably feeds on other species of Lauraceae in evergreen forest. This species has many different forms in both sexes, which mimic various species of Euploea and Parantica.

This is a variable species, they generally occur in two main groups of forms, brown and black forms with white markings. Forms present in Vietnam including, at least, f. clytia, f. onpape, f. janus, f. papone, f. panope, f. dissimilis, f. dissimillima, f. vitalisi.

Chilasa clytia feeding on Duranta erecta - an extremely popular nectar source for a wide variety of butterflies. Widely cultivated as an ornamental plant in tropical and subtropical gardens throughout the world, and has become naturalized in many places

Presumably f. dissimilis - f. dissimillima is very similar but white streaks appear sullied (unsullied in dissimilis)

 The form dissimilis is regarded as mimic of some Danainae species such as Tirumala limniace, Parantica melaneus...

127. Suada albolineata (The Streaky Grass Bob)

Number: 127
Family: Hesperiidae
Sub-Family: Hesperiinae
Species: Suada albolineata Devyatkin, 2000
Common name(s): The Streaky Grass Bob
Photography location: Huu Lien N.R. (Lang Son Prov.), Tam Dao (Vinh Phuc Prov.)

This species is most closely related to S. swerga (De Niceville, [1884]), the upperside pattern of both species being practically identical. Fresh specimens of S. albolineata can be easily distinguished by the strikingly contrasting veins of the underside; for worn specimens examination of the genitalia is helpful.
I have founded this newly described species at Huu Lien and Tam Dao. It seems to be widely distributed all over the country, its distribution thus overlapping with that of its close rela­tive S. swerga (Devyatkin and al., 2003).

126. Leptosia nina nina (The Psyche)

Number: 126
Family: Pieriidae
Sub-Family: Pieriinae
Species: Leptosia nina nina (Fabricius, 1793)
Common name(s): The Psyche, The Wandering Psyche, The Wandering Snowflake
Photography location: Cuc Phuong N.P. (Ninh Binh Prov.)

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.

Until now, I only saw Leptosia nina one time, at Cuc Phuong N.P., but I miserably failed to get any decent shots. So I have nothing to show here but a voucher specimen below, sorry for that.
 

125. Discophora deo fruhstorferi (The Banded Duffer)

Number: 125
Family: Nymphaliidae
Sub-Family: Amathusiinae
Species: Discophora deo fruhstorferi Stichel,1901
Common name(s): The Banded Duffer
Photography location: Tam Dao foothills (Vinh Phuc Prov.)

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).

Discophora species currently known in Vietnam: sondaica, deo, timora and aestheta - the latter described in 2003 from S.Vietnam, Dong Nai Prov., Cat Tien National Park.

124. Parnara cf. ganga (The Continental Swift)

Number: 124
Family: Hesperiidae
Sub-Family: Hesperiinae
Species: Parnara cf. ganga (Evans, 1937)
Common name(s): The Continental Swift
Photography location: Huu Lien Nature Reserve (Lang Son Prov.)

Five Parnara species are listed by Monastyrskii & Devyatkin (2016) from Vietnam viz P. apostata, P. bada, P. ganga, P. batta and P. guttata. The latter flies from China, Korea and Japan to Himalaya and central Asia. 

Parnara species show a great similarity of the external features and it is very difficult 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. 

Photographed in open agricultural land

A close-up view of the forewing (FW) upperside, illustrating post-discal spots in spaces 2-4, 6-7, no cell spots. Hindwing (HW) discal spots in spaces 2-5 large, spot 6 absent.
FW 13 mm in this specimen

P. guttata is larger (FW 15-19 mm),with both FW cell spots present.
P. apostata is much darker.
In P. bada, HW spots in spaces 2-5 small and irregular and may be absent.

Another supposed Parnara ganga from Mt. Tam Dao (foothills, open area).
Note the position of wings : usually for a Hesperiine, the adults commonly bask with the forewings held at a 45° angle, and the hindwings held flat.

123. Borbo cinnara (The Rice Swift)

Number: 123
Family: Hesperiidae
Sub-Family: Hesperiinae
Species: Borbo cinnara (Wallace, 1866)
Common name(s): The Rice Swift, The Formosan Swift
Photography location: Huu Lien N.R. (Lang Son Prov.)

B. cinnara show ochreous or dull yellow-brown underside, with greenish body hairs.
The hindwing has whitish spots in spaces 2-4 and 6, no cell spot. The spot in space 4 is typically small or even absent (this is the case here).

Borbo cinnara always have a spot 1b in both sexes on the upperside - absent or faint in Pseudoborbo bevani.
