11-cis-Vaccenyl acetate (cVA) is a volatile chemical compound that acts as a pheromone in Drosophila and at least one species of longhorn beetle.

The odorant receptor subunit Or67d was shown to be necessary for detection of cVA.

[2] The sensory neurons expressing Or67d send projections to the glomerulus DA1.

Moreover, the projection neurons that connect to DA1 have sexually dimorphic arborizations in the higher brain centers (esp.
