L. dispar is subject to predation from invertebrate species as well as parasitoids (Phryxe vulgaris).[1] During pre-diapause invertebrate predation is responsible for a large proportion of mortality.[6] Parasitoids are commonly found in post-diapause larvae, and results in the death of late, instar larvae.[6] Vertebrate predators often include reed-nesting birds amphibians and small mammals.[6]
