Black death-feigning beetle (Cryptoglossa variolosa), in the Rio Salado Habitat Restoration Area, Phoenix, Arizona. 

When prodded this large beetle gave a very convincing act, playing dead. There wasn’t a dry eye in the house. I give its performance three damp hankies.  

Desert senna (Senna covesii), in the Rio Salado Habitat Restoration Area, Phoenix, Arizona.

Other common names for this plant are Coues’s or Coves’s senna, and rattleweed or rattlebox, the latter referring to the sound of seeds in their pods.
