221. Taraka hamada mendesia (The Forest Pierrot)

Number: 221
Family: Lycaeniidae
Sub-Family: Miletiinae
Species: Taraka hamada mendesia Fruhstorfer, 1918
Common name(s): The Forest Pierrot
Photography location: Tam Dao (Vinh Phuc Prov.)

Taraka hamada is an aphidophagous lycaenid butterfly occuring from India to Japan. Widespread, but not common.

It looks similar to the Common Pierrot (Castalius rosimon) at first glance but you would notice that the spotting pattern is quite different in detail. And notice the unusually fluffy legs. The thing that makes the species special is its carnivorous habits: the caterpillars don't eat plants like most butterfly caterpillars, they feed on scale insects and aphids.

220. Matapa aria/druna

Number: 220
Family: Hesperiidae

Common name(s): 
Photography location: Foothills of Tam Dao (Vinh Phuc Prov.)

Four species of Matapa are recorded from Vietnam: cresta, aria, druna and sasivarna.
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
From the shot below, I am unable to come to a firm identification.

Sub-Family : Hesperiinae
Species: Baoris farri (Moore, 1878)

Baoris farri sunbathing on leaves. Note the spotless hindwing.
This quite large skipper is recorded throughout the country.

The forewing has hyaline spots in spaces 2-4, 6-8 and 2 cell spots. The female is usually fully spotted and has an additional non-hyaline spot in space 1b on the forewing (visible in this shot). The hindwing does not bear any spot, but the male has a black hair tuft in the cell on top of a scent pouch (hence "Paintbrush" in its common name).

217. Coladenia agni sundae/agnioides

Number: 217
Family: Hesperiidae
Sub-Family : Pyrgiinae
Species: Coladenia agni sundae or C. agnioides

According to A. Monastyrskii (pers. comm.), C. agnioides is similar to C. agni sundae, but the male has a conspicuous white dot outward the central brand in the space 1b of the underside of the forewing. My specimen is a female therefore it is difficult to make a conclusion.

Sub-Family: Coeliadinae
Species: Badamia exclamationis Fabricius, 1775
Common name(s): The Brown Awl, The Narrow-winged Awl
Photography location: Xuan Son National Park (Phu Tho Prov.)

Only two species make up this genus, one restricted to a number of Pacific islands, the other very  widely distributed, from Pakistan to the Pacific islands and SE Australia.

Badamia exclamationis is readily distinguished from other awls by the elongate fore wing and shape of the hind wing which has a recurve along the margin near the tornus.

UpF dark brown with three pale yellow central spots. UpH with a dark-brown tornal patch and a pale yellow subtornal spot. Underside of both wings grey-brown. The large abdomen is characterized by black and yellow banding.

The range extends from India, China and the Philippines, through Indonesia to mainland New Guinea and adjacent islands, northern and eastern Australia, the Salomon Islands, New Caledonia and Fiji. Badamia exclamationis is known to migrate in vast flights. Locally the species can be so numerous that its food plants (Terminalia) are completely defoliated (Common and Waterhouse, 1981).

This crepuscular Hesperid flies actively early in the morning and late in the evening, whereas it usually pitches under a leaf and is loath to move during the daytime. Hopefully, one day, I will get a better shot.

199. Matapa cresta (The Fringed Branded Redeye)

Number: 199
Family: Hesperiidae
Sub-Family : Hesperiinae
Species: Matapa cresta Evans, 1949
Common name(s): The Fringed Branded Redeye 
Photography location: Foothills of Tam Dao (Vinh Phuc Prov.)

The skipper genus Matapa, described by Moore in 1881 with Ismene aria  Moore, 1866 as the type species, is a small group of the family Hesperiidae. The members of the genus share the following  characters: the eyes are red, wings are dark brown above and below without spots in both sexes, the  hindwing cell at vein M3 is acutely produced, the males of all but M. deprivata  have a stigma on the  upperside of the forewing in spaces Cu1 and Cu2. The genus is comprised of 9 species, which occur  mainly in Oriental region. The species have interesting habits, probably all being mainly crepuscular (de Jong, 1983).
Four species of Matapa are recorded from Vietnam: cresta, aria, druna and sasivarna.

Photo taken without flash - with flash, it really alter its appearance. Lost a lot of sharpness (area very dark, so very high ISO settings) but it doesn't matter, photo looks more natural! Note the extensive pale area on the underside of forewing, distinctly lighter than ground colour. Basal part of hindwing also paler, but less conspicuously.

198. Koruthaialos rubecula hector (The Narrow-banded Velvet Bob)

Number: 198
Family: Hesperiidae
Sub-Family : Hesperiinae
Species: Koruthaialos rubecula hector Watson, 1893
Common name(s): The Narrow-banded Velvet Bob
Photography location : Cat Ba National Park (Hai Phong City)

The genus Koruthaialos comprises of 4 species, all of which being limited to the Oriental region. In Vietnam 3 are recorded - rubecula, sindu and butleri.
Butleri is unique for the genus in having no oblique orange band on forewing.

Tonkin and S. Annam, respectively, are the type-localities of gopaka Frühst, and avidha Frühst., both synonyms of hector. The subspecific division of rubecula is rather complicated by its individual and seasonal variability and, in particular, by the existence of bandless specimens found occasionally throughout the species range (Evans, 1949).

This species is very closely related to K.sindu. But in sindu the orange band is wider, almost of equal width throughout, and extends as far as the leading edge of the forewings.
Moreover the third segment of palpi is short and stout in sindu, long and slender in rubecula.

195. Thaduka multicaudata multicaudata (The Many-tailed Oakblue)

Number: 195
Family: Lycaeniidae
Sub-Family: Thecliinae
Species: Thaduka multicaudata multicaudata Moore, 1878
Common name(s): The Many-tailed Oakblue
Photography location: Hàm Yên District (Tuyen Quang Prov.)

In the field, I thought at fist that it was an Arhopala sp.. But when I returned home, a little research on the Internet revealed that it was in fact Thaduka multicaudata. Found in a thin strip of streamside forest running through agricultual fields in Tuyen Quang Prov.

Un is dark brown marked like Arhopala species, but note the FW pointed sidewardly at apex, HW with three distinct tails and dentate margin.

Sexes are alike. UP is silvery blue with broad black borders.
