So that’s a bit random but I was thinking about resting/camping in D&D and then how STIRGES should preferably feed on sleeping targets and act more like their real-world counterpart, the vampire bat. And yeah, we might say I got down the rabbit hole…

The sanguivore stirge should not be seen as predator but in fact as a parasite (it doesn’t wish to eat you, just to steal some of your blood, that’s parasitic in nature). Sometimes the boundary between the two gets blurry, for example many species of leeches in the real world are often both – stealing blood from animals and also swallowing micro-organisms.

I’ll not go into truly gruesome territory over here (there’s plenty of it when we talk about parasites) but suffice to say, I think including parasitic behavior within your fantasy ecology can definitely add some kind of unforgiving nature ambiance.

In my own game, in my Jungles of Chult campaign, I had giant parasitoid wasps (the mounts of wasp-riding goblins) that laid their eggs inside giant spiders and also fed on the spider-like sentient Araneas. The Araneas turned to the adventurers for help against this threat in exchange for precious spider silk vestments.

For you see, I’m a big fan of Gyagaxian Naturalism in my ttrpgs.

And here’s an entertaining video from Unnatural History Channel, highly recommend this channel if you’re into that kind of stuff:
