Bee


The worker

This is the smallest bee, 13-17 millimetres long. The worker bee gathers food for the hive, cleans the hive and helps rear the young. The worker bee collects nectar and water through its long mouthpiece called a proboscis. Its tongue is used to suck the nectar from the flowers. On its hind legs there are pollen 'baskets' to carry the pollen back to the hive.

The Drone

These are the future fathers. Their only task is to mate with the Queen bee. Once the drone mates with the Queen bee he dies. Drones have no other real purpose. They cannot forage because their mouthpieces are too short for collecting nectar. They cannot make pollen. They cannot defend the hive because they have no sting. They cannot make beeswax. Their role is to help the Queen bee breed.

The Queen Bee

The queen is the largest bee and each normal colony has only one. Her sole purpose is to lay eggs. She is the mother of the hive. She leaves the hive only to mate or when the hive reproduces by swarming. Her body is especially formed for egg-laying. Fertilized eggs hatch into larvae. These grub-like larvae become either workers or queens. Larvae who are fed Royal jelly only during rearing become the queens.

Eggs hatch into larvae in three days. Workers take 21 days to reach maturity from when the egg is laid (drones 24 days, queens 16 days).

The leopard (Panthera pardus) is an Old World mammal of the Felidae family and the smallest of the four big cats of the genus Panthera, which also consists of the tiger, lion and jaguar. Once distributed across southern Eurasia and Africa, from Korea to South Africa and Spain, it has disappeared from much of its former range and now chiefly occurs in subsaharan Africa. There are fragmented populations in Israel, Indochina, Malaysia, and western China. Despite the loss of range and continued population declines, the cat remains a least-concern species;[1] its numbers are greater than that of the other Panthera species, all of which face more acute conservation concerns.

This spotted cat has relatively short legs and a long body, with a massive skull. It most closely resembles the jaguar physically, although it is usually smaller and of slighter build. Its fur is marked with rosettes which lack internal spots, unlike those of the jaguar. Leopards that are melanistic, either completely black or very dark in coloration, are one of the big cats known colloquially as black panthers.

The species' success in the wild owes in part to its opportunistic hunting behaviour and its adaptability to a variety of habitats. The leopard consumes virtually any animal it can catch and ranges from rainforest to desert. Its ecological role resembles that of the similarly-sized cougar in the Americas. Physically, the spotted cat most closely resembles the jaguar, although it is of lighter build. The leopard and jaguar may have shared ancestry, though the leopard might be more closely related to the lion.
