2021 Annual Report for: Geometridae / Geometrinae
For species seen in 2021 that had less than or equal to 100 records, full details are included; for more common species, the earliest, latest and highest count by vice-county are shown. The narrative for each species is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species. The tables in each species account summarise the previous status, and that for the current year.
For the maps, all records prior to 2021 are shown by a blue dot (the larger the dot, the more recent), with the current year's records shown in red. As previous records are superimposed on any report for 2021, new sites have greater emphasis (i.e. will show as 'more red').
In the species accounts, an asterisk next to a location indicates a new 10km square record; earliest ever dates are highlighted in orange, and latest ever in red. Initials in the species accounts refer to the recorders listed here. Please get in touch if you identify any omissions or errors, in particular if you have records that have yet to be submitted. Details of how to submit records can be found here.

70.303 [B&F: 1674] Little Emerald Jodis lactearia (Linnaeus, 1758) - Common
Common in open woodland, mature hedgerows, scrubby heathland, moorland and grassland throughout much of England, Wales and western Scotland. In Hampshire and on the Isle of Wight still widespread in all three vice-counties but surely much less common than formerly. Wingspan 23-26 mm. The most likely confusion species is Small Grass Emerald Chlorissa viridata, which see for differences. Larva feeds on Downy Birch, Silver Birch, Hazel, Hawthorn and Blackthorn, over-wintering as a pupa.

70.306 [B&F: 1670] Small Grass Emerald Chlorissa viridata (Linnaeus, 1758) - Nationally Scarce
Nationally scarce (Na) in damp heathland and mosses in parts of southern England and in north-western England, where now very rare. Fairly common in boggy areas of the New Forest, and eastwards to Emer Bog although not in recent years; formerly on heathy ground in Botley Wood, but not since 1960. No recent record from the Isle of Wight, and the old record for northern Hampshire remains unconfirmed. Wingspan 24-27 mm. Similar to Little Emerald Jodis lactearia, but cross-lines straighter. Larva feeds on Heather, Cross-leaved Heath, Creeping Willow, Gorse and other woody plants, over-wintering as a pupa.
