Cheilomenes sexmaculata (Fabricius) (Coleoptera: Coccinellidae) "zigzag ladybug" is a potential biological controller, predator of aphids and mealybugs. The objective of this research was to determine the morphological characteristics of the different biological states of Determine the morphological characteristics of the different biological states of C. sexmaculata, as well as the morphological characteristics of the genitalia. The biological sample was obtained from alfalfa and corn crops in the town of Moche, then it was transferred to the laboratory in 250 mL plastic containers. and the dissection, assembly, recognition, measurement, and description were carried out with the help of the Amscope brand microscope and stereoscope with camera and integrated program. The egg is greenish-yellow, shiny, and tapered. Larva I dark brown, with semicircular epicranial suture and presence of setiferous tubercles with two hairs, one free and the other on the chalaza from the pronotum to the VIII abdominal segment, larva II dark brown, with U-shaped epicranial suture with presence of a stiff hair with a pointed apex, called a scolus; larvae III and IV are dark brown with the presence of yellowish spots, a “U”-shaped epicranial suture and a scolus from the pronotum to the VIII abdominal segment; Light orange pupa with black spots, oval in shape, adults are roundish, with elytra that vary in color between yellow, red and orange, with black margins. The male genitalia present a curved sipho in the apical part, the parameres and the basal lobe are symmetrical, in the female genitalia the spermatheca is curved and has some folds around the cornu. It is concluded that Cheilomenes sexmaculata presents a difference in size that is shown in tables and figures, as well as in the morphological characteristics, the color of the egg and of the four larval instars, as well as the shape of the epicranial suture and the covering of hairs present on the body, the pupa with a different color and the adult with sexual dimorphism in the head and pronotum, in addition to the color of its elytra of the four types of specimens and morphological characterization of the genitalia.
