General comments
Widespread resident in Hertfordshire. Currently absent from Middlesex

The Square-spotted Clay has been regarded recently as a rare moth in Britain and until recently was categorised as a UK Biodiversity Action Plan species and included in English Nature's 'Species Recovery Programme'. In spite of this, it almost immediately recovered. Although the inclusion was wise, the moth has nevertheless demonstrated that sometimes enormous population swings are quite normal. Rather more worrying is the absence from Middlesex.
