Megalostomis
Megalostomis is a genus of case-bearing leaf beetles in the family Chrysomelidae, subfamily Cryptocephalinae. The genus contains 42 valid species following a 2013 taxonomic revision, with most species distributed in the Americas. Members of this genus are notable for their ant associations and case-bearing larval biology. The genus is divided into seven subgenera, including the arid-adapted subgenus Scaphigenia found in South America.
Rhopalosiphum enigmae
cattail aphid
Rhopalosiphum enigmae is a cattail aphid species in the family Aphididae, first described by Hottes and Frison in 1931. Recent taxonomic work has clarified its classification, including a new synonymy. The species is associated with cattail habitats and has documented relationships with ants and parasitoid wasps, though specific details of these associations remain limited in available literature.
Theclinae
hairstreaks, elfins
Theclinae is a subfamily of Lycaenidae butterflies comprising hairstreaks, elfins, and related groups. Members are characterized by small to medium size, often with tail-like projections on the hindwings and intricate underside patterns. Many species exhibit myrmecophilous relationships with ants, and larvae possess a specialized dorsal gland (Newcomer's gland) that secretes sugary fluids to attract ant protectors. The group shows high diversity in tropical regions, particularly the Neotropics and Southeast Asia, with fewer migratory species compared to other butterfly groups.
