摄影师Sam Droege把镜头对准了细小的昆虫，鲜少有人这样对待这些精致的小生物。
The USGS Native Bee Inventory and Monitoring Program designs and develops large and small scale surveys for native bees. As part of that program we also develop identification tools and keys for native bee species. One aspect of creating those tools is creating accurate and detailed pictures of native bees and the plants and insects they interact with.
