• Agathirsia

  Agathirsia is a genus of parasitic wasps in the family Braconidae (subfamily Agathidinae). Species exhibit interspecific variation in mouthpart length, with glossa lengths ranging from short to elongated. Adult wasps visit flowers for carbohydrate resources, and mouthpart length influences feeding efficiency and floral visitation patterns. Pollen analysis indicates that species with elongated mouthparts access similar nectar sources regardless of tongue length, while short-tongued species show distinct floral associations.
