 Picture page about Autumnal Moth Epirrita autumnata
The caterpillar of the Autumnal Moth usually differs from the larva of the November Moth.
In June or July the caterpillar of the Autumnal Moth descends down the tree and goes underground to pupate in a cocoon.
The Autumnal Moth has only one generation a year, which is on the wing in October and the beginning of November.

 Autumnal Moth - Wikipedia, the free encyclopedia
The Autumnal Moth (Epirrita autumnata) is a moth of the family Geometridae.
In Lapland, in some years the numerous autumnal moth larvae may kill square miles of birch forests on mountains.
This species is very similar to the November Moth and Pale November Moth and identification is usually only possible by examining the genitalia.

 November Moth   (Site not responding. Last check: 2007-10-08)
The November Moth (Epirrita dilutata) is a moth of the family Geometridae.
The species is extremely similar to two of its relatives, Pale November Moth and Autumnal Moth, and they cannot usually be separated without examination of the genitalia.
The November Moth flies at night from September to November and is attracted to light and sometimes to nectar-rich flowers.

 Maternal effects in gypsy moth: only sex ratio varies with population density Ecology - Find Articles   (Site not responding. Last check: 2007-10-08)
For gypsy moth, Lymantria dispar, a large body of evidence shows that high population density precipitates changes in the ballooning behavior of larvae (Leonard 1968, Leonard 1970, Diss et al.
Rossiter (1991a) distinguishes non-nutritional factors (crowding, temperature) from nutritional (leaf quality) factors that influence the parental generation of moths and then, primarily through the quantity or quality of egg provisions, increase phenotypic variation in the life-history traits of offspring.
In Rossiter's studies, gypsy moths that fed on trees with greater herbivore damage produced offspring that were heavier as pupae (female pupae were [approximately]25% heavier and males [approximately]10% heavier with an increase in defoliation from 0 to 50%).

 Environment & Nature News - Pest screen for eucalypts - 15/05/2002
Researchers at CSIRO Entomology and CRC for Sustainable Production Forestry have been trying to determine which leaves are the most attractive to the moths for laying their eggs on.
The moths attack eucalypt plantations - on the mainland these are all Tasmanian blue gum (Eucalyptus globulus) - laying their eggs on the leaves.
One experimental approach is to obtain sample leaves from individual trees and determine the quantity of wax, then get some information about their composition and details on the toughness and the water content of the leaves.

The amazing run of rare moths at the traps continued with the overnight capture of a Pale Shoulder, the first Observatory record but unfortunately flying off before it could be photographed, a very worn Cosmopolitan (third observatory record), another Convolvulus Hawk-moth and a new pyralid for the Observatory, a Nephopteryx angustella.
Moth trapping produced the scarce pyralid Dioryctria sylvestrella, a Langmaid's Yellow Underwing and a Dark Spectacle.
Moth trapping produced a Miller and a Doubled-lobed along with the pyralids Gymnancyla canella and Ephestia parasitella.

Most people start by learning how to identify the macro moths as they are generally much easier to identify than micros.
If you refer to the Moth Sightings page of the UTB website you will be able to find out which moths are being reported at the time and this could also narrow down the moth(s) you are trying to identify.
However, you may prefer not to keep a specimen at all, in which case the moth can still be recorded as an ‘aggregate’ species.

The moth lays eggs in the autumn in the branches of birches near buds, where the larva flakes off the next spring, just when ‘the table is set’, the leaves are ready for eating.
These moths live in Southern Finland, too, but apparently birches are there more resistant and big damages aren’t able to occur.

 Within-season variability of pupal period in the autumnal moth: a bet-hedging strategy? Ecology - Find Articles   (Site not responding. Last check: 2007-10-08)
In this study, we aim to find an evolutionary explanation for the high within-season variability in pupal period in a moth species, focussing on the possibility that variation in this continuous trait represents a bet-hedging strategy.
This model was further used to estimate phenotypic selection for increased variance in eclosion date, caused by unpredictable weather during the reproductive period of this moth.
Farther to the south, Epirrita moths may be in flight as late as November in Britain and central Europe (Koch 1984, Skinner 1984).

Accordingly, our two data sets do not support the assumption of a higher annual growth rate in autumnal moth populations subsequent to mast seeding of the host, thereby contradicting the predictions of the mast depression hypothesis.
Temperatures, when indexed by the North Atlantic Oscillation and accumulated thermal sums, were observed to correlate with the abundance or rate of population change of the autumnal moth.
The factors underlying the regular population cycles of the autumnal moth, however, remain unidentified.

Reading Waring, it says that a distinguishing feature between the November and the Autumnal moths is position of the central wing spot ie Pale November and Autumnal it is inbetween the wing bars and November it is obscured by the wing bar.
Additionally, in Autumnal Moth the wing bar is more sharply angled round the central spot.

Perhaps this shows that we have been working harder and more systematically and that we have some new and very active recorders, but there is clear evidence that several species are extending their range and turning up for the first time in light-traps that have been run regularly for many years.
We did record two species new to the County and one of these was the rare immigrant, the Ni Moth, which was taken on Hilbre Island (SJ18) on the 21st June 1996 by Gavin Broad.
