[1] F. carpenteri is named in honor of the paleoentomologist Dr Frank Carpenter, for his vast knowledge and interest in Raphidioptera.

Dr. Michael S. Engel first studied and described the species after finding the specimen in the Harvard collections.

There are also a number of small areas with "schimmel", a type of white mold sometimes present on arthropods in amber.

The wings are hyaline with brown coloration of the vein structure and are slightly fuscous at the base.

[2] Along with F. erigena F. carpenteri is one of two known from the baltic amber deposits, while F. cerdanica is from the Miocene of Spain and F. exusta is from the Eocene of the Florissant Formation, Colorado.
