Some costs have components that are fixed and some that are variable. One example is wages for your sales force. A portion of the wage for a salesperson may be a fixed salary and the rest may be sales commission.
Hornets are the largest eusocial wasps, reaching up to 45 millimetres (1.8 inches) in length. Yellowjackets are black-and-yellow wasps of the genus Vespula or Dolichovespula (some can be black-and-white, the most notable of these being the bald-faced hornet, Dolichovespula maculata).
Wasps are usually shiny or appear smooth, while bees are usually fuzzy. Yellow jackets are a ground-nesting wasp that is common. They are about the size of or a little larger than a honeybee and have bright yellow and black bands around their bodies. Hornets are simply large wasps. Most hornets are at least double the size of a yellow jacket and their aggressiveness is at least double as well! Hornets quickly respond to threats by counter-attacking entities that are potentially harmful to their nest or the larvae and pupae within.
