Custom Puzzle: "This Puzzle Has No 10-Letter Word"

[Calilasseia]

I tried to create a custom 10-letter puzzle to share with everyone, but for some reason, I was presented with the error message "This puzzle has no 10-letter word".

Which means that spiderling, as in a newly hatched spider, is missing from the database. An omission I consider in need of remedying, even without my passion for invertebrate zoology.

No "bug" specialist, I, but I do know the word spiderling.  I wonder if the word shows up in Charlotte's Web?

Spiderling is in a few dictionaries, and is used occasionally. I can't answer the question that occurred to birdy, whether the word is used in E B White's Charlotte's Web, but it is certainly used by people writing about the book. For example, in a 2010 Gizmodo article about spiders' silk:

The sight of these gossamer wisps sailing along in the sky has brought to mind otherworldly creatures such as fairies, too. But fairies, with their piloted wings, are really more like dragonflies and somehow less endearing than the real-life speck-sized aeronauts who, in the words of a spiderling in E. B. White's Charlotte's Web, go "wherever the wind takes us. High, low. Near, far. East, west. North, south."

I'll add spiderling, but as a rare word, so the only time anyone will encounter it is in a player-created puzzle like the one Calilasseia created.
