Ladybug

Ladybugs are great to have since they eat aphids.  In large enough numbers, aphids can do serious damage to vegetables. These orange ladybugs are actually called Asian Lady Beetles, as they were originally native to eastern asia.  They were introduced to the US as a biocontrol agent since 1916.
