Forms: 1900s– scotophil, 1900s– scotophile, 1900s– skotophil, 1900s– skotophile.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: scoto- comb. form², -phile comb. form.

Etymology: < scoto- comb. form² + -phile comb. form, after German skotophil (E. Bünning 1944, in Flora 138 95). Compare photophil adj. 2. Compare scotophilic adj.

Biology.

Designating a phase of a diurnal cycle during which consistent darkness is required for certain developmental processes, such as flowering in plants and diapause in insects; of or relating to such a phase. Contrasted with photophil (photophil adj. 2).

1949 Herbage Abstr. 19 129/2 This inner rhythm within the plant consists of two phases: one adjusted to light, the other to darkness. These are denoted as photophile and scotophile respectively.

1960 Cold Spring Harbor Symp. Quantitative Biol. 25 257 In this part of the rhythm the endodiurnal system is in the scotophile state according to Bünning.

1971 New Scientist 29 July 254/2 The circadian rhythm [of house finches] was imagined to comprise two half cycles,..one of which was reckoned to be dark-requiring (scotophil).

2005 Jrnl. Insect Physiol. 51 601/2 (caption) The dark areas below the midline [represent] the ‘scotophil’ or dark-requiring phases (equivalent to subjective night).
