Ok, you’ve answered what kind of bugs the members of Pink Floyd would be, but what kind of bugs would the Beatles be? (I mean, they’d be beetles, but the question remains what kind of beetles they’d be individually)
Also, how did you come to know so much about bugs?
to answer your second question: childhood special interest.
to answer your first question:
Paul: seven-spotted ladybug (Coccinella septempunctata)
Ladybugs are the cute beetle. Everyone agrees they're adorable, even begrudgingly by people who hate bugs. Despite their popularity, however, people don't tend to know anything about them and they are actually quite complex and fascinating. They can also cause quite a stink if you get them upset, even if they look innocent.
John: bombardier beetle (Brachinus crepitans)
This beetle is generally harmless, but when they feel threatened or under pressure they have rather a explosive defense mechanism (releasing a spray of noxious chemicals that can reach a boil!) There is a lot of disagreement amongst experts over the reasons for this behavior, and as a result a lot of misinformation has been spread about them.
George: nocturnal dung beetle (Scarabaeus satyrus)
Dung beetles put up with a lot of shit, but there's much more to them than meets the eye. Many species are cosmically conscious: that is, they use the stars, the sun, and/or the moon to navigate. No wonder they appear as a spiritual symbol in many cultures.
Ringo: clavate tortoise beetle (Plagiometriona clavata)
They go through a bit of a rough childhood, but when they grow up, they turn into a resilient and often quite social beetle. Although they still have their protective shell, but as you see they're one of the most transparent beetles. They are an unsung favorite of specialists.
Faul: false ladybird (Endomychus coccineus)
