A NEW SPECIES OF MELANAGROMYZA (DIPTERA, AGROMYZIDAE) MINING LEAVES OF BROMELIA PINGUIN (BROMELIACEAE) IN A DRY FOREST IN COSTA RICA

摘要

Melanagromyza resales, sp. nov., from Costa Pica is described and its natural history is summarized. Larvae are miners in leaves of Bromelia pinguin, a large terrestrial rosette plant. They form conspicuous longitudinal mines that may be over Im long. Adult emergence is virtually simultaneous for all individuals, probably triggered by temperature cues. Populations are low for many generations with brief periods of abundance. [References: 12]
