Problems with honey bee pollinators has increased interest in native pollinators. Pollinators are a guild which is a group of not-necessarily-related insects that share a lifestyle but may differ greatly in taxonomy. Many people who want to study pollinators lack the taxonomic expertise to correctly identify them. The USGS is trying to facilitate studies by producing series of high quality pictorial guides.
One of the scientists, Sam Droege, uses macrophotography, computer stacking software and post processing to produce high quality insect images. His work has been featured on FlickrBlog which is worth checking out. The USGS also has a YouTube video featuring Sam Droege giving tips on photographing insects including inexpensive devices for lighting.
