Genus Guides
2Dinocampini is a tribe of within the Euphorinae of the Braconidae. Members of this tribe are known to exhibit complex mating including formation, as documented in the recently described Napo townsendi. The tribe is represented in the Neotropical region, with observations from Ecuadorian cloud forest .

Identification
Dinocampini can be distinguished from other Euphorinae tribes by genitalic and wing venation characters; detailed morphological requires examination of metasomal and associated structures related to production. -level identification within the tribe relies on subtle differences in wing shape, coloration patterns, and male genitalia.

Habitat
Tropical and subtropical forest , particularly cloud forest with high humidity and dense vegetation.
Distribution
Neotropical region; documented from Ecuador with iNaturalist observations suggesting broader distribution in Central and South America.
Behavior
Males of at least one (Napo townsendi) form — of 2–7 individuals on leaf surfaces for mate attraction. Males employ spread-winged calling displays, releasing from lateral metasomal applied to wings and hind legs. Aggregated males engage in agonistic displays and physical fighting. Upon female approach, males perform brief wing-vibration courtship before mounting. Copulation lasts approximately 3–4 minutes. Displaying deter predatory arthropods, particularly salticid spiders, through apparent chemical defense rather than physical weaponry.
Ecological Role
; members of this tribe function as agents by parasitizing insects.
Human Relevance
Potential value in programs due to lifestyle; research interest in complex mating systems and chemical defense mechanisms.
Similar Taxa
- Other Euphorinae tribesDinocampini shares the Euphorinae with tribes such as Cosmophorini and Peristropini, but differs in male lekking and specialized structures for production.
More Details
Chemical defense hypothesis
The spread-winged calling posture and release in Napo townsendi may serve dual functions: intrasexual agonistic display among males and aposematic warning to . This suggests of sexual and defensive signaling.
Research gaps
Most behavioral and ecological knowledge derives from a single recently described (Napo townsendi); broader patterns across Dinocampini remain undocumented.
