Phanagenia bombycina
(Cresson, 1867)
Phanagenia is a solitary in the , tribe Auplopini. It constructs delicate mud barrel nests to house paralyzed and developing . The is found east of the Rocky Mountains and is slightly larger than related Auplopus species. Uniquely, it frequently builds its mud inside the abandoned nests of the pipe organ mud dauber (Trypoxylon politum).

Identification
Distinguished from the smaller, widespread Auplopus by larger body size. Differentiated from other mud-nest building by its characteristic of constructing mud barrel nests, often inside pre-existing Trypoxylon politum nests. Geographic distribution east of the Rocky Mountains helps separate it from western .
Appearance
Slightly larger than related Auplopus . Specific morphological details not documented in available sources.
Habitat
Associated with sheltered locations suitable for mud nest construction. Often found in proximity to abandoned pipe organ mud dauber nests, which are adhered to flat surfaces such as rock , building walls, or other man-made structures.
Distribution
East of the Rocky Mountains, North America.
Diet
, which are paralyzed and stored as provisions for .
Life Cycle
Female constructs a mud barrel nest, provisions it with paralyzed , lays a single , and seals the . The feeds on the paralyzed , molts into a , and emerges as an . Development may include in the pupal stage.
Behavior
Nests solitarily. Constructs delicate mud barrel nests, often placing them inside abandoned nests of Trypoxylon politum. Females hunt to provision nests. Not aggressive; females do not defend nests actively and will not attack humans.
Ecological Role
of . Provides nesting substrate for potential (-parasite relationships poorly documented).
Human Relevance
Nests may be found on human structures. Not aggressive; poses minimal risk. Nest rearing by observers could contribute to scientific knowledge of - relationships.
Similar Taxa
- AuplopusSmaller body size; widespread distribution; constructs similar mud barrel nests but does not typically nest inside Trypoxylon nests
- Trypoxylon politumDifferent (Crabronidae); constructs linear mud tube nests with multiple ; male-female cooperative nesting absent in Phanagenia
More Details
Nest architecture
Mud barrel construction is characteristic of tribe Auplopini, but P. is notable for frequently utilizing pre-existing Trypoxylon politum nests as a substrate
Research opportunity
Rearing mud nests may yield rather than the expected , contributing to poorly understood host-parasite relationships
