2021 Annual Report for: Noctuidae / Acronictinae
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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
73.034 [B&F: 2277] Scarce Merveille du Jour Moma alpium (Osbeck, 1778) - Nationally Scarce
A rare Red Data Book species, almost entirely restricted to large areas of well-established oak forest, formerly in southern England from Cornwall to Kent, now only common in the New Forest, west Sussex and the Kentish Weald. In Hampshire and on the Isle of Wight still quite common in New Forest oak woodland, and still present in woods near Wickham and in Havant Thicket, but it has disappeared from other localities where it was fairly common up until the 1950s. Unrecorded on the Isle of Wight since the turn of the 20th Century, until one was reported in 2021. Wingspan 34-40 mm. Unmistakable. Larva feeds on Pedunculate Oak and Sessile Oak, over-wintering as a pupa.

73.036 [B&F: 2281] Alder Moth Acronicta alni (Linnaeus, 1767) - Local
Local in broad-leaved woodland and scrub throughout much of England and Wales, also in western Ireland. In Hampshire and on the Isle of Wight considered to be a very rare moth until the advent of m.v. light; it is now known to be widespread and fairly common, though only recorded from the north of the Island. Wingspan 35-42 mm. Larva feeds on various broad-leaved trees, including Downy Birch, Alder and Goat Willow, over-wintering as a pupa.

73.037 [B&F: 2283] Dark Dagger Acronicta tridens ([Denis & Schiffermüller], 1775) - Common
Common in woodland, fens, gardens and a wide range of other habitats throughout much of England and Wales. In Hampshire and on the Isle of Wight very much less common than Grey Dagger, although undoubtedly under-recorded owing to similarity to that species. Wingspan 33-44 mm. Very similar to Grey Dagger A. psi, from which separated only by dissection of the genitalia. The larvae of the two species are readily identifiable. Larva feeds on various broad-leaved trees and shrubs, including Wild Rose, Cultivated Rose, Hawthorn, Blackthorn and Goat Willow, over-wintering as a pupa.

Very similar to Dark Dagger A. tridens, from which separated only by dissection of the genitalia. The larvae of the two species are readily identifiable. Larva feeds on various broad-leaved trees and shrubs, including Blackthorn, Hawthorn, Apple, Birch, Common Lime, English Elm and Rowan, over-wintering as a pupa.

In Hampshire and on the Isle of Wight widespread and common in all three vice-counties. Wingspan 35-43 mm.

Local in a wide variety of habitats, including hedgerows, woodland, calcareous grassland, fens and hillsides throughout the British Isles. In Hampshire widespread and locally frequent in the south, less common in the north and on the Isle of Wight. Wingspan 35-42 mm. Only likely to be confused with dark forms of Poplar Grey Acronicta megacephala, but smaller, with more rounded apex. Larva feeds predominantly on Ash, but also on Alder and Hazel, over-wintering as a pupa.

73.048 [B&F: 2397] Small Yellow Underwing Panemeria tenebrata (Scopoli, 1763) - Local
Local in flower meadows, calcareous grassland, roadside verges and sea cliffs throughout England and Wales. In Hampshire and on the Isle of Wight scattered colonies of this species occur on meadows and downs, but rare in the New Forest. Wingspan 18-20 mm. Flies during the day in sunshine. Hindwing primrose-yellow with broad black border to one-third and heavy black suffusion at base (MBGBI Vol 10), together with day-flying habit and small size preclude confusion with any other British moth, although it has been compared to the pyralid Pyrausta aurata. Larva feeds on seed capsules of Common Mouse-ear and Field Mouse-ear, over-wintering as a pupa.
