Ugliest Bug: grassbug

Seed Beetle (Algarobius prosopis)

Habitat: Seed beetles and their larvae feed on beans and seeds of other plants, and their larvae develop inside a single seed.

Interesting facts: Seed beetles are also commonly called “bean weevils,” even though they are not weevils in the strict sense since they lack a long snout. In Arizona, they are common in the seeds of mesquite and “algarrobo” trees.
