You can get a degree in the field of aerodynamics the construction of aircraft but still not understand how and why, some creatures that a priori cannot fly if you rely on the foundations of science but they are unsurpassed flyers.
The list of such creatures is huge in theory the cockchafer should not fly and there is nothing that could help the heavy hawkmoth butterfly that you see in the photograph rise into the air.
Even bees they are also among those for whom flying is contraindicated lol.
Yes, you know this living in the Hive, we come across a lot of pripons which in theory do not give us the opportunity to fly very high, but this does not take away our desire to fly and despite all ill-wishers, we fly!
It's incredible but quite obvious and I'm glad about it.
