Why Do Bees Have 5 Eyes?
1)The two large eyes at the side of the head (known as 'compound eyes') are used for picking up shapes and colours in the immediate environment, whilst the three small eyes on the top of the head (known as the 'ocelli') are important for navigation and orientation.
2)bees are not alone in the insect world for having 5 eyes, and specifically for having 3 ocelli on the top of the head: dragonflies, hornets, wasps, and grasshoppers also have them, among others.
3)Ocelli are used by bees for orientation and navigation according to the position of the sun.
4)Bees are trichromatic – just like humans. However, humans base their colour vision on the colours red, green and blue, where as bees base their colour vision on blue, green and UV. Bees cannot see red, but visit red flowers because they are able to see the UV markings on the petals.
HORNET:
1)Hornets have stingers used to kill prey and defend nests. Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine.[8][9] Individual hornets can sting repeatedly. Unlike honey bees, hornets do not die after stinging because their stingers are very finely barbed.
Single hornet stings are not in themselves fatal, except sometimes to allergic victims.[10] Multiple stings by hornets (other than V. crabro) may be fatal because of highly toxic species-specific components of their venom.[11]
The stings of the Asian giant hornet (V. mandarinia) are among the most venomous known,[10] and are thought to cause 30–50 human deaths annually in Japan.
2)The colony can reach a size of 700 workers.
3)Hornets eat bees and their larvae. Hornets are predators, especially of honey bees.
