This is just a random article about some details on flies (house fly, blow fly, drone fly), bees (bumble bee, honey bee) and wasps (common wasp, german wasp).
I was thinking of adding this to a talk page on the wikipedia, but I doubted whether such observation on a talk page would be accepted. So instead, I made this page on my own wiki, under my own policies.
I'm not sure if very many people will see this, because there aren't that many users that contribute here, oh well!
Longish, amber with dark stripes, pollen sacks, black antennae, thick black legs
Barbed sting, can sting other insects repeatedly, but will usually lose stingers after stinging people due to thickness of human's skin (Workers) Straight sting with small barbs, is usually capable of stinging other insects and animals repeatedly (Queens)
More aggressive than bumblebees but still mostly non-aggressive
Longish, yellow abdomen with black stripes with black dots that connect with stripes, black antennae, thin yellow legs. Usually has a vertical black stripe in centre of face. Common wasps are usually smaller than German wasps according to history
Straight sting with small barbs, is usually capable of stinging other insects and animals repeatedly. Queen wasps are reported to have more painful stings than the workers
Aggressive (usually more aggressive than german wasps). Their nests are typically found in the ground or in buildings. Their nests are typically a light brown, and are made from dead or rotten wood
Deep buzzing (calmer and higher than the buzz of a bumble bee)
Fat and hairy, gold with black stripes, cream on back of abdomen, black antennae, thick black legs
Straight sting with small barbs, is usually capable of stinging other insects and animals repeatedly
Gentle, less aggressive than wasps or honey bees, will usually only sting if in serious danger
Pitch varies with each bumble bee, usually quite deep buzzing (louder and deeper than the buzz of a wasp)
For Blow Flies, their buzzing pitches can range from being a tenor, to being a baritone, depending on the blow fly in question, and how big they are.
For Common and German Wasps, their buzzing pitch typically matches that of a baritone. Their buzzing is usually quite deep in comparison to the buzzing of house flies, blow flies, drone flies, and honey bees.
For Bumble Bees, their buzzing pitch can range from being a tenor, to being a bass, depending on the bumble bee in question, and how big they are. Their buzzing is usually louder and deeper than the buzzing of a wasp.
