HORTICULTURE

Detailed explanation-1: -Apis dorsata workers can be up to 3 cm (1.2 in) in length, which is almost twice the length of an Apis mellifera worker; thus they are known as the giant honey bees.

Detailed explanation-2: -Apis laboriosa is the largest extant honey bee species in the world with a body length slightly larger than Apis dorsata (Figure 3). Apis laboriosa workers average just over 1.2 in (3 cm) in length. The scutellum (dorsal side of thorax) is dark brown to black with long yellowish hairs.

Detailed explanation-3: -The bee, Megachile pluto, also known as Wallace’s giant bee, is a massive unit. It is the largest bee in the world, four times larger than a honeybee and measuring about the length of a human thumb. Huge mandibles hang like dastardly garden shears from its head.
