What 螙 means
It is an old form of 蠹, a word for wood-boring insects. In modern Chinese, 螙 is an obsolete variant, so read it as 蠹 unless a text is preserving an older form.
The Chinese character dictionary 《玉篇》 lists 螙 under 蠹 as 古文, meaning an old written form. Its entry carries the image in 《說文》, another Chinese dictionary, of insects inside wood. The compound 蠹書蟲 means a book-eating insect and also became a metaphor for someone absorbed in books.
How do I type 螙?
In Cangjie, enter 木中戈戈 (DLII); Pinyin may list it as dù. Cangjie is a shape-based Chinese input method; Pinyin writes Mandarin syllables in Latin letters.
Type dù or du4 in a Pinyin input method, then select 螙 if it appears. Because this variant is rare, an input method may not offer it.
Rare and old-fashioned; 蠹 is the usual form in modern Chinese.
In ordinary modern writing, 螙 can look like a mistake; use 蠹 unless preserving an older form.
