Main: (Geometridae / Sterrhinae)
70.018 [B&F: 1715] Plain Wave (Idaea straminata) (Borkhausen, 1794)

 

Notes: Local in open woodland, scrubby heathland, hedgerows, rough grassland and gardens throughout much of the British Isles. In Hampshire local and uncommon but probably overlooked, and some of the sight records that have been submitted may have been unwarrantedly rejected; most records are from the New Forest and from Pamber Forest and Silchester. Very scarce on the Isle of Wight, with just three records so far this century. Wingspan 28-33 mm. Most likely to be confused with f. remutata of Riband Wave I. aversata, but in the latter species the postmedian fascia is kinked where it meets the costa, and the fascia are generally darker. Larva feeds on various herbaceous plants.
