Cremnoptini
Genus Guides
1- Cremnops(Pegasus wasps)
Cremnoptini is a tribe of within the Braconidae. Members are small to minute wasps that parasitize the larval stages of various insects. The tribe is relatively small and understudied compared to other braconid groups. Cremnoptini wasps are characterized by reduced wing venation and compact body forms.

Identification
Distinguished from other braconid tribes by the combination of reduced wing venation (forewings with 2 or fewer closed ), compact body form, and specific details of the metasomal structure. Separation from the closely related tribe Aphidiini requires examination of wing venation patterns and petiolar structure. Identification to level typically requires microscopic examination of morphological characters.

Appearance
Small to minute , usually under 5 mm in length. Body typically compact with reduced wing venation; forewings often with few closed . usually short to medium in length. Coloration varies but often dark brown to black, sometimes with pale markings.
Habitat
Found in diverse terrestrial including forests, grasslands, and agricultural areas. Associated with habitats supporting their insects.
Distribution
Recorded from multiple continents including North America, Europe, Asia, and Australia. Distribution appears to be widespread but patchily documented due to the small size and understudied nature of the group.
Diet
Larval stages are ; do not feed or feed only on nectar and other sugar sources. Specific associations are poorly documented for many .
Life Cycle
Complete with , larval, pupal, and stages. Larvae develop internally within insects, eventually killing the host. Details of duration and developmental stages are not well documented for most .
Behavior
are generally inconspicuous and rarely observed directly. Females seek out larvae and deposit internally. Some may use chemical cues to locate hosts.
Ecological Role
Act as agents by parasitizing other insects. Contribute to of various herbivorous insects, though specific ecological impacts are poorly quantified.
Human Relevance
Potential value in of pest insects, though not widely used commercially due to limited research. Generally harmless to humans; cannot sting.

Taxonomic status
Cremnoptini has been subject to taxonomic revision; some authorities have treated it as a subtribe or synonymized it with other groups. Current classification follows recent molecular phylogenetic studies supporting its recognition as a distinct tribe.
Research limitations
Most remain poorly known due to small size, cryptic habits, and difficulty in collection. Many species have been described from few specimens, and biological data are sparse.
