205. Baoris farri (The Bamboo Paintbrush Swift)

Number: 205
Family: Hesperiidae
Sub-Family : Hesperiinae
Species: Baoris farri (Moore, 1878)
Common name(s): The Bamboo Paintbrush Swif
Photography location: Tam Dao foothills (Vinh Phuc Prov.)

Four species of Baoris are recorded from Vietnam: B. farri, B. oceia, B. penicillata, B. pagana.

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).

204. Coladenia agni sundae/agnioides

Number: 204
Family: Hesperiidae
Sub-Family : Pyrgiinae
Species: Coladenia agni sundae or C. agnioides
Common name(s):
Photography location: Tam Dao foothills (Vinh Phuc Prov.)

According to Monastyrskii  & Devyatkin (2016), 6 species of Coladenia are recorded from Vietnam: C. tanya, C. agni sundae, C. indrani uposathra, C. agnioides, C. laxmi sobrina, C. koiwayai (=C. fenestrata).

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.

Type locality: "Chiem-Hoa", central Tonkin.

190. Badamia exclamationis (The Brown Awl)

Family: Hesperiidae
Sub-Family: Coeliadinae
Species: Badamia exclamationis Fabricius, 1775
Common name(s): The Brown Awl, The Narrow-winged Awl
Photography location: Xuan Son N.P. (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.
