Yes, I love those beetles, but not many people believe you when they're told they're called 'cockchafers'! There were (and still are!) many varieties in Africa, including tiny ones with immensely powerful, serrated front legs. If you closed them gently in your hand, they'd force their way between your fingers until you had to release them, and they also made tiny squeaking noises.
I adored them and because they were so sweet, I called them 'sweetie beetles'. One of my uncles, who was also working in Africa, called in to see us. He was quite excited as he was just starting work with an entomologist on pest control for the Grain Marketing Board. I was busy playing with a couple of the beetles and he asked what species they were. "These," I said, giving him one to hold, "are sweetie beetles."
A few days later, out in the field with the rather masculine woman entomologist, he found a few of the chafers. "I know what they are," he boasted, anxious to show off his new-found knowledge. "Aha," said the bug lady, "and what are they called, then?"
"They're sweetie beetles," said my uncle, proudly. After she finished wiping the tears of laughter from her eyes, she told him what their real names were, and I remained unforgiven forever.
