Early stages: Strophedra weirana

Another often overlooked and under recorded species can be found in its larval stage on Beech right now.  The feeding signs are quite obvious, so one worth keeping an eye out for.

Early stage excesses

To say that the last few weeks have been productive in terms of early stage finds - mainly leaf miners but also cases and galls - would be an understatement.

Whilst we all seem to have suffered a dearth of adults to the traps this year, with tales of crashes in numbers of usually abundant species becoming clear as we all start to analyse the 2012 figures in detail, here in East Kent I am falling over early stages at every turn.

By way of illustration, here are some figures from the last 15 days i.e. October so far:

213 out of 320 total records (66%) are for early stages
4907 out of 5160 total individuals(95%) are for early stages
75 species recorded as early stages

The most abundant early stages are:
Phyllonorycter coryli - 1126 mines
P. platani- 1505 mines
P. corylifoliella - 355 mines

Other finds include Phyllocnistis xenia, Stigmella aceris, Bucculatrix thoracella, Phyllonorycter platanoidella, Coleophora laricella, Ectoedemia heringella, Parornix fagivora, Strophedra weirana

Miners, miners everywhere

The profusion of leaf miners is still very much in evidence; just this last week have totalled around 2000 individuals of a wide range of species from many food plants. Here's a few of the latest finds:

 Stigmella tityrella
 

Parornix fagivora


Bucculatrix thoracella
 

Stigmella basiguttella 

Early Stages: Hawthorn miners in abundance

All of the hawthorn hedgerows I look at are currently covered in mines of a range of species, here are four species from the last couple of days:

Ectoedemia atricollis
 


Parornix anglicella
 

Phyllonorycter oxyacanthae

Phyllonorycter corylifoliella

Early stages: Adaina microdactyla

The 'bore holes' and associated galls caused by the larvae of this species are relatively easy to find right now; I found a handful in 2-3 minutes on my way to pick up the kids from school.






Opening up the stems gently will generally reveal the larva inside...

More mining gems

Whilst we all seem to have suffered with records to the traps, leaf mines are in abundance everywhere right now here in East Kent.

Here's a few more from recent days...

Stigmella continuella


Stigmella betulicola


Stigmella basiguttella


Phyllonorycter esperella

Phyllocnistis unipunctella

Leucoptera malifoliella

Stigmella plagicolella


Scrobipalpa costella


Bedellia somnulentella


Tischeria ekebladella
