• Lucilia silvarum

  common toad fly, Marsh Greenbottle Fly

  Lucilia silvarum is a blow fly in the family Calliphoridae, first described by Johann Wilhelm Meigen in 1826. Adults are 4.5–10 mm with metallic green coloration and plumose aristae, making them difficult to distinguish from related green bottle flies. The species has a Holarctic distribution across North America and Europe. Recent research has clarified its ecological role: it is primarily saprophagous on carrion and was identified as a primary colonizer of domestic cats in experimental studies, contradicting earlier assumptions that it was strictly associated with amphibian myiasis.

• Xyleborus celsus

  Hickory Timber Beetle

  Xyleborus celsus, commonly known as the hickory timber beetle, is a bivoltine ambrosia beetle native to North America. It specializes in colonizing stressed or dying black hickory trees (Carya texana) and other hickory species. The species overwinters as adults and completes development from egg to adult in approximately 35 days. Unlike some invasive congenerics, it appears to be a native primary colonizer of weakened trees rather than an aggressive killer of healthy hosts.
