Diurnea lipsiella

Diurnea lipsiella (aka the November Tubic) is a micro moth in the Chimabachidae family. It is locally, but widely distributed across the UK, with Oak (Quercus spp.) and Bilberry (Vaccinium myrtillus) being the preferred larval food plants. As with other members of the Chimabachid moths, the females are brachypterous and therefore flightless. The males however, have a forewing length of 10-12mm and are on the wing in October and November (hence their very imaginative vernacular name).

Whenever the weather has been suitable this semester, we have tried to run two moths traps on the UEA campus. On the night of 31st October we set two traps as usual: one with an actinic bulb and one with a mercury vapour bulb. When we checked the traps in the morning, there were quite a few moths in and around the traps, including 26 November Moth agg. (Epirrita dilutata agg.), four December Moths (Poecilocampa populi), two Sprawlers (Asteroscopus sphinx), two Feathered Thorns (Colotois pennaria) and singles of Diamond-back Moth (Plutella xylostella) and Red-green Carpet (Chloroclysta siterata). Also in the trap was one Diurnea lipsiella, a new species to me, and apparently a new species for the UEA campus too!

The Sprawler

The Sprawler (Asteroscopus sphinx) is a species of resident macro-moth found throughout most of England and Wales, although it is more common in the South. It can be found in broadleaved woodlands, and other well-wooded ares, including some gardens.

It is one of the later-flying species to be found in Britain, with adults being on the wing from mid-October to early December. The species frequently comes to light, with males usually arriving from midnight onwards, and females arriving earlier.

This species only has one generation each year and survives the winter by overwintering as eggs, which are laid in small crevices on the trunks of trees. The eggs hatch in April and the larvae feed nocturnally on a variety of tree species, including Pedunculate Oak, Blackthorn and Small-leaved Elm until early-June when they pupate in a cocoon beneath the soil surface.

The larvae have a habit of throwing their head back as a defence mechanism, and this behaviour is where the English name 'Sprawler' comes from.

It is classed as a UK Biodiversity Action Plan species in England due to an 83% decline in its UK population over a 35 year period (1968-2002) and its use as an indicator species for the winder environment.

Over the last two weeks I have been helping run a few moth traps on campus. Considering the time of year we have done quite well for variety, and in 3 nights of trapping with both an actinic and MV bulb a total of 87 individuals of 16 species have been caught. So far, seven of the species caught have been new to me which is very nice, taking my moth list up to 597 and PSL total to 1186. I'm hoping to reach 600 moths and 1200 overall by the end of 2017 so I have my work cut out a bit, but hopefully a few outings around Norfolk and Hampshire over Christmas will easily take me up to my targets.
