Reading this newspaper article from the Amarillo Daily News of 11 April 1951, I get the distinct impression that the reporter might is perhaps being just a little sarcastic:

A new book speculates that pilots of flying saucers are super-bees from Mars, two inches long and quite beautiful.

[…]

One report was that flying saucers travel 18,000 miles an hour, with sudden stops and turns. Heard says no pilot shaped like a human being could withstand the force and pressure of such movement. But insects might—and so maybe the Martians are bees.

‘A creature with eyes like brilliant cut diamonds, with a head of sapphire, a thorax of emerald, and abdomen of ruby, wings like opal, legs like topaz—such a body would be worthy of this super-mind.’

[…]

The super-bees have been real gentlemen so far, taking care not to crash into man’s airplanes. In fact, ‘they have behaved with a deportment which shows not merely savoir-faire, but real considerateness.’

The full article is here. According to the Wikipedia article on the author of Is Another World Watching?, Gerald Heard, he started taking LSD in the 1950s. This is possibly not unrelated.
