Overview

Apis laboriosa is the largest species of honey bee known at present. Its distribution is restricted, and some of its nesting behaviors are unique.

Diagnostic characteristics

Specimens of A. laboriosa can be differentiated from other species of honey bees by the following combination of characters:

Forewings fuscous and over 12 mm in length (Fig 2 and 7).
Distal abscissa of vein M in hind wing present (Fig 7).
Nest composed of single comb built under overhangs on vertical cliffs.
Nests are common in high altitudes above 1200 m (Underwood 1986).
Nests consist of a single large comb.

It can be differentiated from the other species in the subgenus A. (Megapis) (i.e. Apis dorsata) by the following combination of characters:

Workers with scutellum black (Fig 5) and metasomal T3–T4 reddish-brown (Fig 3, 6, and 8).
Distribution restricted to the Himalayas.
Found at altitudes from 2500 m up to 4000 m above sea level (Roubik et al. 1985).
Colonies usually nest under cliffs and never in aggregations.
Foragers don’t produce sound during waggle dance.

Host associations

As all species of honey bees, A. laboriosa is polylectic and visits a broad range of plants for food.

Nesting behavior

Nests are constructed in the open and consist of a single comb that almost always hangs from rock cliffs at high altitudes. In contrast with Apis dorsata, there are no reports of nest aggregations for this species.

Diversity

There are no races or variations reported for this species. Apis laboriosa was previously thought to be a subspecies of Apis dorsata.

Distribution

This bee occurs in mountainous areas of Nepal, Bhutan, India, and the province of Yunnan in China (Batra 1995, Ahmad and Roy 2000).
