Most wasps will leave you alone. So just leave them alone.
Yes, some wasps in some situations will sting! And it will hurt! What’s even worse, some people can go into shock or have a fatal allergic reaction from a sting. (My condolences.)
So please be safe and smart. Respect nature, and respect yourself.
On the importance of wasps, see, for example https://www.independent.co.uk/environ...
from which I took this excerpt: "Despite their poor public image, wasps are incredibly important for the world’s economy and ecosystems. Without them, the planet would be pest-ridden to biblical proportions, with much reduced biodiversity. They are a natural asset of a world dominated by humans, providing us with free services that contribute to our economy, society and ecology."
And, without Wasps, Homo sapiens might never have existed, because us and our ancestors could not have competed with all the insects (which Wasps keep limited and under control!) for food. No plants for us! And no plants for the herbivores on which we feed!
Wasps are capable of thermogenesis: in cold weather, they use their wing muscles to warmup before a flight. While a number of people have done work on insect thermogenesis, one person who I am aware of is "Bernd Heinrich (born April 19, 1940 in Bad Polzin, Germany)...a professor emeritus in the biology department at the University of Vermont and...the author of a number of books about nature writing and biology. Heinrich has made major contributions to the study of insect physiology and behavior, as well as bird behavior. " (From: https://en.wikipedia.org/wiki/Bernd_H...)
See, for example, "Thermoregulation in Endothermic Insects" at http://forensicentomologist.com/wp-co...
Bees, too! See, for example: "SUMMARY 1. Honeybees when endothermically heated maintained an elevated head temperature (TH). During free flight at 17 °C TH was approximately 7 °C above ambient temperature (TA). However, during flight at TA near 46 °C, head temperature averaged 3 °C below TA. 2. When tethered bees were heated on the head till TH reached 46 °C, they regurgitated nectar from their honeycrop, held it on their ' tongue', and initiated violent aortic pulsations in the head and in-out movements of the nectar droplet. Temperature changes in the head corresponded with heart pulsations. Head temperature was prevented from rising and was stabilized. 3. The heart pulsations in the abdomen and aortic pulsations in the head (and abdominal ventilatory movements) were often synchronous, but during heating of the head they were often independent of each other in both frequency and amplitude. 4. The fluid droplet was several degrees Centigrade below head, thoracic and ambient temperatures, and it remained in motion in and out of the body. It caused TH to be 4-8 °C lower, by the resulting evaporative cooling, than is possible without the droplet. 5. It is concluded that at low TA the elevation and regulation of TTh automatically results in the elevation of TH. However, at low TH heat flows from the heated thorax to the head, not only by passive conduction but also by physiologically facilitated blood circulation."
