2020 Annual Report for: Noctuidae / Acronictinae

For species seen in 2020 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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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 2020 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 2020, 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.

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.

73.041 [B&F: 2285] Marsh Dagger Acronicta strigosa ([Denis & Schiffermüller], 1775) - Extinct

Formerly an uncommon resident in the fens of Cambridgeshire and Huntingdonshire, last seen in 1930’s. Since which it has appeared in southern England rarely as an immigrant from the continent, in East Sussex in 1996, and at Pagham Harbour, West Sussex, in July 2010, to which can be added one of the more surprising records of recent years, when an individual turned up in JHa’s Bonchurch (VC10) trap on 2 Aug 2015, and which is therefore a first for the Isle of Wight and for our area. Perhaps even more remarkably, the same recorder pulled in a second, on almost the same date in 2020. Wingspan 30-32 mm. Shows a strong black streak medially from base to claviform stigma, and two others in echelon above tornus (MBGBI Vol 10). Larva feeds on Hawthorn and Blackthorn.

73.045 [B&F: 2289] Knot Grass Acronicta rumicis (Linnaeus, 1758) - Common

Common on grassland, heathland, marshes, gardens and a wide range of other habitats throughout much of the British Isles. In Hampshire and on the Isle of Wight widespread and common in all three vice-counties. Wingspan 35-43 mm. Superficially similar to other Acronicta species, it can usually be distinguished by the curved white mark near the rear edge of the forewing, which is normally present even in melanic specimens. Larva feeds on various herbaceous and woody plants, including Broad-leaved Dock, Common Sorrel, Ribwort Plantain, Greater Plantain, Water Mint, Bramble, Hop, Hawthorn and Burnet Rose, over-wintering as a pupa.

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.
