Insect fursonas are actually pretty rare, I haven't encountered many.

I think a big attraction to furries is the creativity and excitement of being different, unique, and how you want to be. Insect based furries are probably rare because they’re not typically seen as desirable and personable in real life

But don’t they dress up as a bug/animal whereas Peter IS part bug? So then he wouldn’t be a furry/buggie

Spiders are one of the most popular bugs to make a fursona out of.

Don't ask me how I know this.
