Here is my modest participation in International Rock Flipping Day. Nothing too exciting. Nothing I haven't seen before. a little darkling beetle
fossil-like white exoskeletons of sow bugs
A black widow, with a small neighbor spider, perhaps another Theridion?
Honestly, this is not the best time of year for looking under rocks at my house. Early spring would be better. But at least there's plenty to be found above and beyond the rocks. More to come.
