Caulocampus

Caulocampus can be distinguished from other Tenthredinidae genera by specific morphological features of the antennae, wing venation, and genitalia, though precise diagnostic characters require specialist examination. Sawflies in this genus lack the narrow petiole (wasp waist) seen in Apocrita, instead showing a broad connection between thorax and abdomen. Accurate identification to species level generally requires reference to taxonomic keys or expert determination.

Documented occurrences are sparse; records exist from North America based on limited specimen and observation data. The full geographic range remains poorly characterized due to low sampling effort.

As with other Tenthredinidae, larvae are likely herbivorous and may function as folivores on host plants, contributing to nutrient cycling and serving as prey for parasitoids and other predators. Specific ecological roles for Caulocampus remain undocumented.

• Other Tenthredinidae generaMany sawfly genera share the general body plan of broad waist, two pairs of membranous wings, and herbivorous larvae; Caulocampus requires examination of antennae structure and genitalia for definitive separation.
• Apocrita (wasps, bees, ants)Sawflies including Caulocampus lack the constricted petiole (wasp waist) that defines Apocrita; this is the most readily visible distinguishing feature in the field.
