FIGURE 7 in Taxonomic revision of the parrot snake Leptophis ahaetulla (Serpentes, Colubridae)

FIGURE 7. Color patterns and color tones variability of Leptophis bocourti: (A) USNM 285488, an adult from Santo Domingo de los Colorados, 47 km S of Centro Cientifico Río Palenque, province of Los Rios and (B) QCAZ 8023, a juvenile from province of Durango, Ecuador. Used under CC BY-NC-ND 4.0 https://bioweb.bio/galeria/Album/Leptophis%20ahaetulla. Note that the dorsal color in adults is essentially green in life, but in the juvenile specimen, the color of scales in dorsal rows 1–2 is yellow (indicated by the arrow). Further, the dorsum of the juvenile lacks the small, irregularly shaped black spots of adults, suggesting a distinct ontogenetic color change. Photos by R.W. McDiarmid (A) and S. Ron (B).
