Sutton & Beaumont, 1989: Recorded from all five vice-counties, and is locally common to abundant.

2012 (CHF): This species can be difficult to separate from females of Micropterix aruncella but calthella has the base of the forewing entirely purple whereas aruncella has purple only on the costa. M. calthella can often be found in good numbers especially on Caltha and Ranunculus flowers.
