I'm tired of content on one topic (impregnation from the womb) not being catalogued, meaning it's hard to find, and creators don't notice it, whereas Leucochloridium became popular as soon as it appeared on pixiv. I have nothing against it, it's just like guro to me, and I don't like that.
In short, I found an author who cataloged all the art (and a couple of games) on the topic of pregnancy + insects as parasites.
Long story short: insects fertilize directly while they in the womb. (BUT WITHOUT: guro, gore, ryona, blood, Leucochloridium)
If anyone is interested, I've included the links.
There will also be links to such artworks, and you can find stories on the topic from the author.(
