WBY: redback arrowheads

More critters from Wild Blue Yonder, a group of arrowheads common in residue-rich areas. They aren't dangerously toxic, but the red stripe on their back indicates to predators that they are foul-tasting. The males tend to gather out in the open on rainy or foggy days to sing, establishing territory and posturing for females.

Some days you're arrowhead #2, other days you're arrowhead #3
