Single-dotted Wave

A reasonably widespread and frequently encountered moth, though in common with many species, numbers have dropped away since 2006, and, in the case of this species, still appear to be declining.

Satin Wave

A scarce and local moth, observed most years in small numbers.&nbsp; The stronghold appears to be the northern edge of the Blackdowns, between Taunton and Chard; it is less frequent than it was in the Quantocks and around Minehead, and very scattered in occurrence and increasingly rare elsewhere, usually on or near calcareous grassland sites.

Dotted Border Wave

Always scarce in the county, it has become increasingly rare in recent years and was last seen in the county in 2014 (Porlock).&nbsp; Relatively recent records from the Quantocks, Merriott and Periton.&nbsp; Associated with dry, acidic sites, which are often under-recorded in Somerset, is possible that populations still exist in these areas.
