Many are unaware of the difference between bees and wasps. In fact, they are both considered dangerous. However, this is not the complete picture. At first glance, they look similar in color, size and in behavior. However, make no mistake the features of bees and wasps are very different.
Moreover, one difference from the bee is their pointed lower abdomens and the narrow "waist," that separates the abdomen from the thorax. We are most familiar with those that are bright warning colors and sometime confused with bees. Most only recall the angry buzz and the piercing of the stinger.
This insect makes up a large assorted collection, with more than 30,000 identified species.
The fact is, this insect is a loner and comes in non-stinging varieties. They do much for humans by controlling insect populations.
Bees are pollinators (the help in food production, yeah) meaning they collect pollen and sip nectar. They're freely found in areas where there are flowers. Bees also drink water. On the other hand, wasps are normally predators that eat insects like caterpillars and flies. However, they like to sip on nectar, too. Also, they draw to the smell of food (human, that is) especially those sugary beverages and beer.
However, insect who harmlessly cross upon a wasp colony or decide to disturb a nest find themselves quickly swarmed. A social wasp in crisis releases a pheromone that sends the other colony residents in defense. Unlike bees, wasps can sting repeatedly. Only the female wasp has a stinger.
Mud daubers and pollen wasps build mud cells in secluded places mainly on the side of walls. Which are equipped with multiple cells, attached to the twigs or against walls. Most other hunter wasps burrow into soil. Some favor not to build nests, but instead choose surroundings like holes in wood.
