Species Guides

3

Horisme is a of geometrid moths in the Larentiinae, established by Jacob Hübner in 1825. The genus contains multiple distributed across Europe and North America. One species, Horisme tersata (Fern ), has been subject to sequencing, revealing a -level assembly of approximately 558 Mb. Species within this genus are associated with specific plants and exhibit characteristic wing patterning useful for identification.

Identification

Members of Horisme can be distinguished from similar by forewing pattern elements. Horisme tersata specifically shows a narrow black streak at rest where the second forewing cross-line aligns with a dark line on the ; it lacks the black streak present in Horisme radicaria and possesses a forewing discal spot. Accurate identification often requires examination of wing pattern details and genitalia.

Habitat

Calcareous hedgerows, scrub, and open woodland. Documented specifically for Horisme tersata in southern Britain.

Distribution

Europe (including Denmark, Norway, Sweden, Italy, Sicily, Malta, United Kingdom) and North America (Vermont, United States).

Seasonality

of Horisme tersata fly mainly June to mid-August.

Diet

Larvae of Horisme tersata feed on Traveller's-joy (Clematis vitalba).

Host Associations

  • Clematis vitalba - larval plantSpecific to Horisme tersata; other associations not documented in available sources.

Life Cycle

Complete with , larval, pupal, and stages. Larval stage of Horisme exoletata has been described and illustrated for the first time in recent literature.

Behavior

come to light. Specific behavioral patterns beyond this attraction to light sources have not been documented in available sources.

Human Relevance

Horisme tersata sequenced as part of Lepidoptera genome project (Wellcome Sanger Institute), contributing to understanding of geometrid evolution and genetics.

Similar Taxa

  • Horisme radicariaSimilar wing patterning but distinguished by presence of black streak and absence of forewing discal spot, versus H. tersata which lacks apical streak and has discal spot.
