Host Associations
- leaf-miners - Dapsilarthra rufiventris forages for patchily-distributed leaf-miners; not specified in available sources
Behavior
Dapsilarthra rufiventris exhibits complex foraging involving multiple sensory modalities. Studies demonstrate use of plant odor as a long-range cue for patch location, visual and acoustic cues for close-range patch location, and discrimination of previously searched leaflets. The responds to sounds emitted by feeding and employs a stopping rule for host search.
Ecological Role
of leaf-mining insects.
Similar Taxa
- DacnusiniBoth Dapsilarthra (Alysiini) and Dacnusini are treated together in major European checklists due to taxonomic proximity and similar ; however, Dapsilarthra belongs to the Alysiini, not Dacnusini
- Chrysocharis pentheusBoth are of leaf-miners studied for behavioral responses to mines; C. pentheus is in Eulophidae rather than Braconidae
