This highly specific HS10 classification covers live larvae of leaf cutter bees (primarily Megachile rotundata), which are commercially important pollinators widely used in alfalfa seed production across North America. Trade in leaf cutter bee larvae is primarily conducted between the United States and Canada, with strict phytosanitary controls to prevent disease and parasite transmission. This niche market is critical to the agricultural seed industry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Leaf cutter bee larvae (Megachile rotundata) are commercially significant pollinators for alfalfa seed production and are traded in substantial volumes between the U.S. and Canada, warranting a dedicated 10-digit classification for accurate trade data collection and regulatory oversight.
The primary trade flow is between Canada and the United States, where larvae are produced in Canada and imported into the U.S. for use in alfalfa fields across western states; shipments require USDA APHIS permits and phytosanitary certification.
Key concerns include chalkbrood fungus (Ascosphaera aggregata), parasitic wasps (Melittobia), and various mite species that can devastate larval populations; health inspections and treatment protocols are required to mitigate these risks.
