Ampedus
click beetles
Ampedus is a large genus of click beetles (Elateridae) comprising approximately 461 recognized species with a cosmopolitan distribution concentrated in the Holarctic region. Adults are characterized by their ability to spring into the air using a click mechanism for predator avoidance. The genus exhibits substantial size variation, with North American species ranging from 3–4 mm to 13–14 mm. Larvae are saproxylic, developing in decaying wood, while adults feed on pollen. Multiple European species are considered endangered due to logging pressures on their forest habitat.
Clinidium rosenbergi
Clinidium rosenbergi is a small ground beetle in the family Rhysodidae, described by R.T. Bell in 1970. It is endemic to the United States with a disjunct distribution spanning the eastern United States east of the Appalachian Mountains, extending to the Delaware River in Pennsylvania, with isolated populations west of the Mississippi River in Missouri. The species measures 6.2–7.8 mm in length. Like other rhysodines, it is associated with decaying wood habitats.
Nasiaeschna pentacantha
Cyrano Darner
Nasiaeschna pentacantha, commonly known as the Cyrano Darner, is a large dragonfly in the family Aeshnidae. It is distinguished by an exceptionally long, upward-curving frons that gives the head a distinctive profile. The species occurs in eastern North America and is associated with forested streams and rivers. Adults are most active in late summer.
Poemeniinae
Poemeniinae is a small subfamily of ichneumonid wasps (Hymenoptera: Ichneumonidae) established by Narayanan & Lal in 1953. Members are ectoparasitoids of wood-boring insects, with hosts including beetle larvae (Cerambycidae, Buprestidae) and xylophilous bees (Apoidea). The subfamily exhibits high local species richness in undisturbed forest habitats, particularly in the Carpathian Mountains where up to 95 species of the broader pimpliform group have been documented in a single 250-hectare forest patch. Taxonomic stability has been limited, with genera such as Podoschistus historically transferred between Xorides, Neoxorides, and other groupings.
Polyporivora polypori
flat-footed fly
Polyporivora polypori is a species of flat-footed fly in the family Platypezidae. The genus Polyporivora is associated with bracket fungi (polypores), though specific host relationships for P. polypori remain poorly documented. The species was described by Willard in 1914. Available records suggest it occurs in forested environments where suitable fungal hosts are present.
Pycnomerini
Pycnomerini is a tribe of beetles in the family Zopheridae, subfamily Zopherinae, first described by Erichson in 1845. The tribe includes the genus Pycnomerus, whose members are primarily saproxylic, inhabiting dead and decaying wood in forest ecosystems. Some species, such as P. rimatara and P. prebblei from Rimatara in French Polynesia, are known only from subfossil material and are considered likely extinct due to habitat destruction. The tribe has a global distribution with documented observations across multiple regions.
Pycnomerus
ironclad beetles
Pycnomerus is a genus of ironclad beetles (family Zopheridae) comprising more than 20 described species. Members are small, elongated beetles with hardened, often sculptured exoskeletons typical of the family. The genus includes both widespread and highly restricted species, with some island endemics now considered extinct due to habitat loss. Several species are associated with dead wood habitats and are classified as saproxylic.
