with galls? something like Aceria eupatorii? https://bladmineerders.nl/parasites/animalia/arthropoda/acari/actinotrichida/prostigmata/eleutherengona/eriophyoidea/eriophyidae/eriophyinae/acerini/aceria/aceria-eupatorii/

"Zombie" ant (Formica sp., https://www.inaturalist.org/observations/91429431) infected by the cercariae of a lancet liver fluke (Dicrocoelium dendriticum) - typical ant's behaviour for the life cycle of this parasite, it climbed on the top of a grass and clamps its mandibles onto it (I've checked, this one was holding hard with mandibles, despite being dead), waiting for some grazing animal to eat this grass and to continue the life cycle of a parasite (see life cycle of Dicrocoelium dendriticum).
