Distribution.
India
: Northeastern region (
Arunachal Pradesh
,
Assam
,
Manipur
,
Meghalaya
,
Sikkim
,
West Bengal
);
Nepal
;
Bhutan
; Mount Everest.
Prey/associated habitat.
Predatory on adelgids and other aphids; associated with
Pineus
sp.
(label data); collected from cabbage fields (
Kapur, 1963a
), and
Quercus
forest (Canepari, 1997);
Taoia indica
(Ghosh & Raychaudhuri)
.
Seasonal occurrence
: Collected during February–June, November, December (data labels).
Notes
. It is a distinctive species common in the northeastern parts of
India
and the live adult is very characteristic and lime green in colour and dead specimens are yellowish brown to dull straw yellow. Kapur (1963) commented on its
type
locality “Dukhun”, which was changed by
Korschefsky
to “Deccan”.
Iablokoff-Khnzorian’s (1982)
record from
Tamil Nadu
in southern
India
is wrong and most likely to be a case of misidentification or mislabelling.
