02Description

Species Profile

Megachile maritima, common name coast leaf-cutter, is a species of leaf-cutter bees in the family Megachilidae. It was described by William Kirby in 1802.

The Coastal Leaf-cutter Bee faces significant threats from coastal development and habitat loss as human activities increasingly encroach upon its specialized shoreline nesting sites. Climate change poses additional risks through sea level rise and increased storm intensity, which can destroy nesting areas and alter the availability of native flowering plants essential for foraging. The species' restricted coastal distribution makes it particularly vulnerable to these localized but intensive pressures.

03Habitat

Habitat & Distribution

Coastal dunes, sandy cliffs, and maritime grasslands along temperate shorelines where it excavates nesting burrows in sandy or soft soil substrates. The species requires proximity to diverse native coastal flowering plants for pollen and nectar collection.
