Thirsty Work . . .

I've always liked wasps, I like their beautiful little faces and colours.

After a long walk around great dixter gardens, I sat down to have a drink. This little one was thirsty too!

ABOUT WASPS

Wasps make up an enormously diverse array of insects, with some 30,000 identified species. We are most familiar with those that are wrapped in bright warning colors—ones that buzz angrily about in groups and threaten us with painful stings.

But most wasps are actually solitary, non-stinging varieties. And all do far more good for humans by controlling pest insect populations than harm.

Differences From Bees

Wasps are distinguishable from bees by their pointed lower abdomens and the narrow "waist," called a petiole, that separates the abdomen from the thorax.

They come in every colour imaginable, from the familiar yellow to brown, metallic blue, and bright red. Generally, the brighter coloured species are in the Vespidae, or stinging wasp, family.

All wasps build nests. Whereas bees secrete a waxy substance to construct their nests, wasps create their familiar papery abodes from wood fibres scraped with their hard mandibles and chewed into a pulp.

Social vs. Solitary Wasps

Wasps are divided into two primary subgroups: social and solitary. Social wasps account for only about a thousand species and include formidable colony-builders, like yellow jackets and hornets.

Social wasp colonies are started from scratch each spring by a queen who was fertilized the previous year and survived the winter by hibernating in a warm place. When she emerges, she builds a small nest and rears a starter brood of worker females.
These workers then take over expanding the nest, building multiple six-sided cells into which the queen continually lays eggs.
By late summer, a colony can have more than 5,000 individuals, all of whom, including the founding queen, die off at winter. Only newly fertilized queens survive the cold to restart the process in spring.

Solitary wasps, by far the largest subgroup, do not form colonies. This group includes some of the wasp family's largest members, like cicada killers and the striking blue-and-orange tarantula hawks, which can both reach 1.5 inches in length. Whereas social wasps use their stingers only for defence, stinging solitary wasps rely on their venom to hunt.

Stingers

Most animals have developed a well-earned fear of stinging wasps and give them a wide berth. Creatures who haplessly stumble upon a wasp colony or have the audacity to disturb a nest will find themselves quickly swarmed. A social wasp in distress emits a pheromone that sends nearby colony members into a defensive, stinging frenzy. Unlike bees, wasps can sting repeatedly. Only females have stingers, which are actually modified egg-laying organs.

Impact on the Ecosystem

Despite the fear they sometimes evoke, wasps are extremely beneficial to humans. Nearly every pest insect on Earth is preyed upon by a wasp species, either for food or as a host for its parasitic larvae. Wasps are so adept at controlling pest populations that the agriculture industry now regularly deploys them to protect crops.
