[1] In June 2021 upon manipulation, a snake of this species presented vocalization, a duration of 0.06 seconds, reaching 3036 Hz in its peak frequency with a modulated note, emitted through exhalation of air through the larynx, being the first record of a snake call in South America.

[3][1] The specific name, catesbyi, is in honor of English naturalist Mark Catesby.

[4] D. catesbyi is found in Bolivia, Brazil, Guyana,[5] Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela.

[6] D. catesbyi lives at altitudes of up to 1,500 m (4,900 ft), in mountainous regions, tropical forests, and lowlands.

[1] D. catesbyi, like all species in the genus Dipsas, preys on arboreal land snails and slugs.
