Found climbing in small backyard rocks with a second matching bug (sorry for the slightly indistinct photo) Abdomen is orange red, black eyes and black heart shape on back. Very faint red line on head.
Approximately 1.2" bug sitting on play structure in backyard.
The much-fêted beavers of Martinez. This family lives in a restored brackish creek and are apparently completely unafraid of people. As a kid I used to go fishing near beavers and they would tail slap and dive if I looked at them wrong from 100 yards. You could practically pet these guys they get so close.
