Even though bees sting, they serve a purpose. so, please be kind to all bees. If you encounter the aggressive ones move away slowly and don't flail about. The sizes in these drawings are very close to, if not, actual size.
As you can see here, Yellow Jackets are not out to sting you... as long as you're still, don't swing your arms, flail about, threaten them or disturb their nest.
Troy has fed all types of bees, from Honey Bees to Wasps, by putting honey on his fingers or palm. He has also proven bees can recognize him as a food source after approximately an hour of feeding them; to the point they will still be looking for him in the same feeding location the next day. He can identify each bee by the unique markings on its thorax.
Bees are dying off at alarming rates all over the world. The main reasons: climate change, exposure to agricultural/yard chemicals, lower tolerance to parasites and stresses along with diminishing nutritional options. All of which lead to suppressed immune systems and death.
Glyphosate, the active herbicide ingredient in Roundup is advertised as being innocuous to wildlife. But when pollinators come in contact with it, the chemical reduces gut bacteria, leaving bees vulnerable to pathogens and premature death.
Neonicotinoids, an insecticide kills bees over an extended period of time and threaten bee queens lowering reproductive rates in the colony. Neonicotinoids also get into waterways and flowers miles away from their use take up the chemical and pass it again to the bees.
Chlorothalonil is the most common of many fungicides targeted at molds and mildews – not insects. But it is now believed fungicides are making bees more susceptible to the deadly Nosema parasite or exacerbating the toxicity of other pesticides.
The stress tolerance of bees is not without limits. One stress bees experience is from being transported to multiple locations across the country from one season to the next for their pollination use. This wears down their immune systems and can cause erratic behavior.
Habitat loss and intensified agriculture lead to diminishing food resources for bees who need a variety of plants to keep the colony healthy. A recent study likened bees feeding on monoculture crops to humans eating only sardines, chocolate or parsnips for a month!
