The life expectancy of a drone is about 90 days. Although the drone is highly specialized to perform one function, mating and continuing the propagation of the hive, they may have other purposes. All bees, when they sense the hive's temperature deviating from proper limits, either generate heat by shivering, or exhaust heat by moving air with ...
Eristalis tenax is a large, stocky bee mimic. The eyes are marbled in black. Males have hovering displays. The average wing length is 9.75–13 mm and their average wingspan is 15 mm. The exact appearance of the drone fly can vary considerably. [7] The abdomen can vary in color from dark brown to orange. [7]
Unlike a bumble bee colony or a paper wasp colony, the life of a honey bee colony is perennial. The three types of honey bees in a hive are: queens (egg-producers), workers (non-reproducing females), and drones (males whose main duty is to find and mate with a queen). Unlike the worker bees, drones do not sting.
Eristalis arbustorum, the European drone fly, is an abundant Northern Hemisphere species of syrphid fly, originally officially described by Linnaeus in 1758 as Musca arbustorum. The name "drone fly" is related to its similar appearance to the drone of the honeybee.

However, with a body length of 17–23 mm, queens have bigger bodies than males or workers. Workers have bodies that are 8.5–16 mm, and males have bodies that are 12–18 mm long. [ 4 ] [ 6 ] The differences in their sizes can be observed by the differences in their larval weight at second instar . [ 8 ]

This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based. These units are thus considered to be human scale and anthropocentric.
