It might make the headaches worse and the TSA (security) might have concerns if you look ill. Other than that it is fine. No true medical harm will come of it other than pain.
Cluster flies are slightly larger than the common house fly. The main difference is in the sucking parts used in the mouth.
Cluster flies primarily feed on nectar, fruit juices, and aphid honeydew. They do not feed on human food or materials found in homes.
Cluster flies can survive in cooler temperatures, but they typically seek shelter in warmer environments during the winter months. At 20 degrees Fahrenheit, the conditions would be too cold for cluster flies to thrive, and they would likely become inactive or die due to the extreme cold. Therefore, without heat in the home, it would be unlikely for cluster flies to live there comfortably.
no
can i fly with a retinal vein thrombosis
It is very unlikely, I know of no tablet that enables one to fly.
The best answer is as far as they have to. Migrating ducks fly thouands of miles, while domestic breeds rarely fly at all.
NO!! If they did, they wouldn't fly!
Yes!!

Honeybees don't actually hibernate, but they won't leave the hive if the temperature is too low. In order to fly a bee has to have a body temperature of at least 80 degrees Fahrenheit (27 degrees Celsius). Although a bee generates body heat as it flies, at air temperatures below about 54 degrees Fahrenheit (12 degrees Celsius) the bee will lose heat faster than it can generate it and will become unable to fly. Below about 50 degrees F (10 C) the bee will become comatose and eventually die. In cold weather, bees cluster within the hive and vibrate their wing muscles to generate heat. This requires a lot of energy and is the reason bees collect nectar for honey: for food during the cold weather.
It took me quite a while to find the answer to this question. But I have been informed by a gentleman in the states that they can fly.
