Identification

The combination of large size (for a ), distinctive elongate horse-like with extended , and red-and-black coloration with smoky helps distinguish Cremnops from other braconids. Within the , species-level identification requires examination of detailed morphological characters and is best accomplished using the provided in the 2015 revision by Tucker et al. The species was previously confused with C. nigrosternum, now synonymized.

Appearance

Members of the Cremnops are relatively large compared to many other , measuring approximately 6–10 mm in length. They possess a distinctive elongate, equine-like with a narrow, extended () that has been compared to the mythological winged horse Pegasus. Coloration typically includes red and black patterns with black or smoky . The elongated mouthparts are adapted for probing flowers for nectar.

Habitat

Terrestrial ; frequent flowers where they use elongated mouthparts to for nectar.

Distribution

Caribbean and North America. Specific locality records are sparse in the provided sources.

Host Associations

Life Cycle

As with other Cremnops , females hunt and lay in them. Typically one develops as an internal per caterpillar, though some species in the are gregarious with several larvae sharing a host.

Behavior
