Spitzwegerich
"Plantago lanceolata" is host to many different species of the order Lepidoptera. Species such as "Junonia coenia, Spilosoma congrua," and "Melitaea cinxia" lay their eggs on "P. lanceolata" plants so they can serve as a food source for the larvae when they hatch. The iridoid glycosides in the plant leaves accumulate in the caterpillars and make them unpalatable to predators.
