Entomological etymology: 螟蛉 (mínglíng)

I'm going through characters with 虫 for my study notes, and I stumbled upon a curious background story.

There's a kind of wasp called 蜾蠃 (guǒluǒ) = potter wasp that was (mistakenly) believed to adopt a kind of caterpillar 螟蛉 (mínglíng).  Hence the line in the Book of Songs:

Quote

《诗经·小雅·小宛》写到：“螟蛉有子，蜾蠃负之”。

Something like: "the 螟蛉 has a son, the 蜾蠃 looks after it".  Based on this, the caterpillar 螟蛉 became a figurative word to mean "adopted son".

It turns out, that's not entomologically accurate, and the wasp larva eat the caterpillars:

Quote

When a cell is completed, the adult wasp typically collects beetle larvae, spiders, or caterpillars and, paralyzing them, places them in the cell to serve as food for a single wasp larva.
