Philanthus multimaculatus
beewolf, bee-hunting wasp
Philanthus multimaculatus is a common North American beewolf wasp in the family Crabronidae. Females are solitary nesters that excavate burrows in sandy soil, often in aggregations with conspecifics. They provision nest cells with paralyzed bees, primarily sweat bees (Halictidae), and lay a single egg on each prey item. Males exhibit territorial behavior, perching on grass stems near nesting areas to intercept females and chase rival males. Adults visit flowers for nectar and serve as pollinators while also functioning as predators that regulate bee populations.
