This is from Cannery Row (my favorite) and is more than a little bit hippie:
On the black earth on which the ice plants bloomed, hundreds of black stink bugs crawled. And many of them stuck their tails up in the air. “Look at all them stink bugs,” Hazel remarked, grateful to the bugs for being there…”What they got their asses up in the air for?”
…”I don’t know why,” [Doc] said. “I looked them up recently–they’re very common animals and one of the commonest things they do is put their tails up in the air. And in all the books there isn’t one mention of the fact that they put their tails up in the air or why.”
Hazel turned one of the stink bugs over with the toe of his wet tennis shoe and the shining black beetle strove madly with floundering legs to get upright again. “Well, why do you think they do it?”
“I think they’re praying,” said Doc.
“What!” Hazel was shocked.
“The remarkable thing,” said Doc, “isn’t that they put their tails up in the air–the really incredibly remarkable thing is that we find it remarkable. We can only use ourselves as yardsticks. If we did something as inexplicable and strange we’d probably be praying–so maybe they’re praying.”
“Let’s get the hell out of here,” said Hazel.”
