Leucoptera caffeina is a butterfly ( moth ) from the family of lyonetiidae (Lyonetiidae). Since the speciesmineson the leaves of the coffee bush (Coffea) and thus causes economic damage in the plantations, it isone of the pests along with other species from the genus Leucoptera .

Way of life
Leucoptera caffeina prefers dry conditions with low humidity and high temperatures. A female lays up to 60 eggs on the leaf surface. The larvae hatch after 20 days. The white caterpillars mine directly under the upper leaf epidermis. For pupation, the larvae spin a cocoon in the lower third of the plant, where the microclimate is more constant. The finished moths have a life expectancy of around two weeks. The adults are nocturnal and are just 6.5 millimeters tall.
Harmful effect
In the case of severe infestation, the coffee plant is mainly damaged by the loss of water, minerals and organic matter, which leads to leaf loss and thus a reduced assimilation capacity. This ultimately leads to a reduction in yield in the plantations.
Occurrence
The animals originally live in Africa , but are z. B. was introduced in South America .
