Finding Caterpillars > Metalmark and Blue Caterpillar Burrows into Host Plant > Caterpillar burrow Spring Azure on Buckwheat

Many lycaenid caterpillars will burrow holes into the flowers or inflorescens from which they feed.  Note the small hole in the flower as caused by this fourth instar Celastrina ladon echo caterpillar.  Other smaller lycaenid caterpillars will burrow right into the inflorescens of some plants.
