Early stages: Nemapogon clematella

It is also worth having a close look at any Hazel branches that have the small black fruiting bodies of the fungus Diatrype disciformis on them, as the larvae of Nemapogon clematella feed within, given away by the tell-tale frass. The last image is of a pupa and cocoon found directly under these fruiting bodies that could be N. clematella, time will tell.

Early stages: Metzneria lappella

Another relatively widespread moth with a commonly occurring food plant whose larvae are easy to find at this time of year - Metzneria lappella.

The often abundant larvae can be found in their winter hibernacula within the seed heads of Greater Burdock.  This hard hibernacula can be felt once the seed head is opened and teasing this apart further will reveal the rather dumpy looking larva.

They are also easy to rear through, just pop a few seed heads in a container and wait...simple.

Early stages: Carcina quercana

Here is a fairly widespread moth, Carcina quercana, with an almost ubiquitous foodplant, bramble.

These are relatively easy to spot right now; the patches of 'windowing' caused by the larvae feeding beneath the leaf can be quite obvious.  On turning the leaves over, the larval spinnings will betray the hiding place of the green larvae.

Definitely one worth keeping an eye out for during the lean times.

Although I'd say this generally about early stage searches and my year list clearly illustrates this as it now stands at 34 species but adult moths total just five species.

Some other micro finds to date this year include:

Metzneria aestivella - larvae in Carline Thistle seed heads
M. lappella - larva in Burdock seed heads
Epinotia immundana - larvae on birch catkins
Ectoedemia heringella mines
Cedestis subfasciella mines
Cochylis roseana - larvae in teasel heads
Endothenia marginana - as above
E. gentianaeana - as above
Limnaecia phragmitella - numerous larvae in Typha seed heads
and cases of Coleophora gryphipennella, C. glaucicolella, C. argentula and C. solitariella.

Micro highlights of 2012

Whilst 2012 didn't set the world on fire with regards to mothing, I still had plenty of highlights, some of which are illustrated in the collage below:

2012 micro moth highlights - adults

All the above from Kent, except the P. oleae, however I did find mines of this species at a garden centre in Canterbury this year, so technically...

Large images, clockwise from top left:
Prays oleae - reared from larvae mining leaves of olive at Wentworth Garden centre, Sth. Yorks,
Ethmia terminella - back garden, East Kent,
Sciota adelphella - back garden, East Kent,
Esperia oliviella - Covert Wood, Kent

Medium images, top: Nemapogon ruricolella - ancient hedgerow, East Kent;

Small images, clockwise from top left: Micropterix tunbergella, Grapholita internana - back garden, East Kent

Check your evergreens

Whilst the winter wind and rain have swept most leaves from the trees and with it any chance of finding leaf miners, it is still worth checking any Evergreen Oak (Quercus ilex) you happen to be passing as there are mines, both vacated and tenanted, still to be found...

Ectoedemia heringella 

This species is known to be expanding its range, so definitely one worth keeping an eye out for, mines can be plentiful, as illustrated below

Early stages: Phyllonorycter platani

This is the most numerous species I have recorded this year, all as leaf mines and all in urban situations up and down the country, including Leeds, Norwich and all around Canterbury.

Alder Phyll fills out the year list

Although late in the year, still managed to add another to the year list last week in the shape of Phyllonorycter strigulatella leaf mines on Grey Alder.

Phyllonorycter strigulatella leaf mines

Whilst many leaves had already fallen, those that remained held plenty of mines from this species as well as those of P. rajella, P. kleemannella and P. stettinensis.
