Leucochrysa pavida is a green lacewing which incorporates lichen fragments into its larval debris packets and pupal cocoons. Since only minute lichen fragments are harvested, identification of lichens utilized in debris packet and pupal cocoon construction is difficult using morphological characteristics. A comparison of the chemical profiles of epiphytic, corticolous lichens at Tower Rock Recreation Area in Hardin Country, Illinois, with lichen substances identified by thin-layer chromatographic analysis of debris packet and pupal cocoon extracts revealed that L. pavida larvae selectively harvest and use lichen thallus fragments from Lecanora strobilina, Lepraria sp. #1, and Myelochroa aurulenta in the construction of debris packets and pupal co |
