We are conducting a research project on the effects of parasitoids on the butterfly species associated with the Stinging Nettle (Urtica dioica). This 3 year project will look at range-expanding species, the Comma and Peacock and the impacts that they have on established species such as the Small Tortoiseshell via shared parasitoids (wasps and flies). In doing so, we may document the first records of the invasive parasitoid Sturmia bella in the north west of England. We are therefore operating in association with the Butterfly Conservation Small Tortoiseshell research project organised by Dr. Owen Lewis at the University of Oxford.

If you notice any of these species anywhere in Lancashire or Cumbria, we would be very grateful for the following information about the sighting(s):

1. Location of sighting (place name, county, plus Ordnance Survey grid reference or postcode).

2. Date of sighting

3. How many webs (or individual Comma caterpillars) you could see in the location

4. The approximate size of the nettle patch (e.g. 1 metre in diameter); whether there are other patches in the vicinity and if so approximately how many.

5. If possible a digital photo would be excellent too

The earlier that you spot the caterpillars and can give us the information the better, so that we can monitor parasitism throughout the life-cycle.
