Photoreceptors8.0 ± 0.1 (1149)8.4 ± 0.6 (1000)
Cone cells4.0 ± 0.1 (146)4.4 ± 0.7 (143)
1° pigment cells2.0 ± 0.1 (146)2.2 ± 0.4 (143)
2° and 3° pigment cells4.0 ± 0.0 (10)5.3 ± 0.3 (10)
Total of averages18.0 ± 0.220.3 ± 1.0

Average numbers of cells per ommatidium are shown with the standard deviations. For photoreceptors, cone, and 1° pigment cells, the numbers of ommatidia scored are in parentheses. For 2° and 3° pigment cells, the numbers of cell areas scored are shown. See materials and methods for details. The R8 photoreceptor was not explicitly scored. However, the presence of one R8 per ommatidium can be assumed because each ommatidium is founded by an R8.
