Earthquake hazard map showing peak ground accelerations having a 2 percent probability of being exceeded in 50 years, for a firm rock site. Black box outlines Yellowstone region. The map is based on the most recent USGS models for the conterminous U.S. (2018), Hawaii (1998), and Alaska (2007).

The December 18, 2019, overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water pond in Halema‘uma‘u crater.

The December 18 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water pond in Halema‘uma‘u crater. A band of warm temperatures persists along the new cliff formed during the 2018 subsidence.

Unknown Beetle. Found on Andelot Farms in Kent County. I am not sure what genus this is. Seems like Acmaeodera, but it doesn't match and of the region's species I know. Captured in June. Photographed by Brooke Alexander.

New Lense set up! This is my first stack from a new lens set up that I learned from Johan Ingles-Le Nobel's lovely Extreme Macro layout.

Andrena miserabilis, showing sharp pronotal corners

Andrena nigrihirta, female, Isle Royale National Park, Michigan

Sample of Dead Birds that struck buildings in Washington D.C. during the Fall and Spring of 2012 in a short stretch of streets from Union Station to the Convention Center, photo stitched together from 18 separate hi res shots.

Here lie the birds killed while striking a set of buildings surveyed during the migration season in 2013 in Washington D.C. The birds were picked up by the group Lights Out Washington D.C.

Catching up, again, with our backlog of pictures. Here is one of the most common Andrena species in the mid-Atlantic. Andrena cressonii. Photographed by Dejen Mengis.

The very common Two-striped Planthopper, Notice the veining in the wing that mimics the veins of a very tiny leaf.

This is picture 1 from a 12 picture series by Matt Buffington at the USDA Parastitic Hymentoptera group at the Smithsonian. Matt's group uses a system very similar to ours to photograph and stack this super tiny wasp. Perhaps one of the most spectacular of the eucoiline wasps out there, species of Acantheucoela are native to South America.

Monster cleptoparasite, this dramatic species is a nest parasite of bees in the genus Centris and is endemic to South America. Note the one shot of the lovely expanded tibial spurs. I do not know their function, but it may have to do with nest invasions, either digging or gripping the walls of the nest. Lovely metallic blue / purple colors.

Bee tool, from a monster cleptoparasite, endemic to South America. Note the lovely expanded tibial spurs. I do not know their function, but it may have to do with nest invasions of Centris, either digging or gripping the walls of the nest. Lovely metallic blue / purple colors. From the Packer Lab.

The red maple, Acer rubrum, often one of the most dominant trees in deciduous woods in the East. It blooms very early in the spring and provides pollen and nectar to the set of bees, and flower flies, that come out early.
