Toyon trees

Toyon is a common brush in our part of the Sierra Nevada foothills. A common BRUSH. This location, above Sonora, had a high density of toyon as trees. That is unusual.

 

 

 

Floating wasps

These wasps would land directly on the water, drink, and take off. That was unusual to see. Dr. Lynn Kimsey thinks they are one of our native Polistes paper wasps.

Pack rat nest

While doing a large poison oak job, Alex Hartung and I found a pack rat nest on a steep brush and tree-covered hillside on Oman Drive, Soulsbyville. An interior live oak had fallen over, still green, with roots intact. There were bits of bark and small branches strewn thickly over the top of the nest, which stood about three feet high. There was no way such material could have accumulated naturally like this on that tree. It was a pack rat nest. June 19, 2021. Photos by Alex Hartung.

Winged female thief ant

Columbia Ca 6-22-21

Winged female thief ant. 3/8 inches long.

Dr. Philip Ward confirmed the ID. He pointed out that the taxonomy of thief ants (Solenopsis species in the erstwhile subgenus Diplorhoptrum) is in a rather unsatisfactory state. This queen could be called Solenopsis molesta, the most common North American species, but the boundaries of that species remain unclear.
