Arthropodan syninclusions in the Late Eocene Rovno amber were examined using c2 to reveal correlation of the component groups (some taxa of Diptera, ants, aphids, and mites) supposedly indicative of the biocoenotic relationships in the ancient amber forest. Three tightly correlated groups were identified, representing a putative aerial plankton guild (Chironomidae + Ceratopogonidae) and two tree-trunk guilds, one of which (Dolichopodidae + Germaraphis) is possibly connected to more open or/and more hygrophilous habitats than the other (Sciara zone Diptera + “Acarus” rhombeus). The ants were not linked with any of the above components.
