Leaf Mine Hunting

Leaf Mine Hunting:

Can anyone help Laura with her project (see below):

Good morning,

My name is Laura, I am an MSc student from the University of Glamorgan in South Wales and am conducting my research project on the invasive Horse-Chestnut Leaf-Miner (Camararia ohridella). The caterpillars of this moth live inside the leaves of the Horse-Chestnut tree.

LEAF-MINER HUNT - Saturday the 25th of June 2011:

I need help in collecting data about the distribution of this Moth in the UK and wondered if you might be able to pass this message onto your local moth groups to see if they are interested in getting involved in leaf-miner hunting.

Everyone would need to find their nearest Horse-Chestnut tree on the 25th of June 2011 and have a look at the middle 'finger' (leaflet) of 10 different leaves from a single tree.
I need to know how many 'mines' there are in each of these leaflets (these are small brown circles or lines on the leaf, easiest to see when the leaf is held up to the light) and the location of the tree (post code, town, etc.), even if there are no mines.

This information will then be put into a map to show the geographic distribution. This will help with my research project into the distribution of the moth and it's parasites.

More information can be found on My Blog http://leafminer.wordpress.com if anyone is interested. I will keep it updated as we approach the big day, with information on how to send your results.

Thank you so much for your help,

Laura Gosset ( 09003053@glam.ac.uk )

Horse Chestnut Leaf-miner (Cameraria ohridella) HUNT:

Good afternoon everyone,

This is just a quick note to remind everyone that the Horse Chestnut Leaf-miner HUNT is on, tomorrow (Saturday - 25/06/2011), moth and tree enthusiasts alike are getting involved with what has turned out to be a national survey day. I have updated the blog with a picture of a leaf effected by fungal disease (Guignardia aesculi) as compared to a 'mine' to help with the identification, I also got a good tip from someone today that looking at the underside of the leaf when held up the light helps to distinguish between numerous interconnected mines.

Please enter the results into the online survey form when you get a chance, I will not be collecting these until Sunday the 3rd of July so no hurry, as long as the survey is conducted on the 25th June. Don't forget that even the absence of the moth is important information.

Happy hunting, and I really appreciate your continued support.

Laura
