Homozygotes have a total lack of ommatidial structure in the eye. Pigment is dispersed as a ring around the edge of the eye ("spectacle" phenotype).
The antennal funiculus is reduced in size in hemizygous males. All large and small basiconic sensilla on the antennal funiculus are missing, and the number of trichoid sensilla on the antennal funiculus is reduced. The number of coeloconic sensilla on the antennal funiculus is normal. The density of the coeloconic sensilla on the antennal funiculus is increased and the density of the trichoid sensilla on the antennal funiculus is decreased compared to wild-type. Most basiconic sensilla on the maxillary palps are normal, although some are reduced in length.
Stable allele.
