lz³⁶ adults have a "spectacle" eye phenotype. Ectopic cell death is seen in third larval instar eye discs.

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).

Mutants display locomotor activity rhythms with circadian periods, though with reduced penetrance (small sample size).

The antennal funiculus is reduced in size in hemizygous males. The number of large and small basiconic sensilla and coeloconic sensilla on the antennal funiculus is slightly reduced. The density of the trichoid sensilla on the antennal funiculus is increased and the density of the coeloconic and basiconic sensilla on the antennal funiculus is decreased compared to wild-type.

A strong lz allele. Adult eye is smooth with a pink eye surface, eye has no lens or cone cell cups, distorted pigment cell layer. eye disc pattern very irregular.

Eyes are greatly reduced in size and have a smooth surface in homozygous flies. Red eye pigment is sparse and confined primarily to the margin of the eye. Tarsal claws are vestigial. The spermathecae and pars ovariae are absent in homozygous females.

spectacle; spermathecae absent; parovaria absent female-sterile Like lz³ in texture, color of eyes, and color of larval Malpighian tubes. Parovaria and spermathecae tend to be abnormal in lz³⁶/+ females (Anderson, 1945). RK1.
