Status

The very small and skinny, beetle hole nesting, Chelostoma philadelphi. A specialist on Philadelphus (mock orange). This species is most commonly seen on the non-native European Mock Orange that was widely planted in the olden days. Its associations with the quite rare native Philadelphus species seems mysterious and there is perhaps more to the story than we currently know (Sam Droege/USGS).
