Butterflies at Fowlescombe

What are butterflies?
Butterflies are invertebrates in the order Lepidoptera (which comes from the Greek 'scale wings'), since the wings of the butterfly consists of a membrane covered by loosely attached scales. Butterflies are fully grown adult insects, and as such don't grow any further, but they under go a four stage life cycle and at each stage they look completely different. EGG, CATERPILLAR, CHRYSALIS and BUTTERFLY
"The length of time each adult butterfly lives depends upon the species that it is and the prevailing weather conditions. For instance a small species such as the common blue may live only for a few days, whereas a peacock may emerge from its pupa in early August, feed up and hibernate, mate and lay eggs in the spring and still be on the wing in early June the following year." Field Studies Council (1998) Guide to the Butterflies of Britain

The transect.
In 2001 a new butterfly transect was set up on the farm, the transect goes through some of the land that is under the farms country side stewardship scheme from the wet meadows at the bottom of the valley through broadleaved woodland and onto permanent grassland. The transect is set up using the Butterfly Conservation guidelines

This transect is split in to nine different sections, each section is given a habitat code and an management/activity code, for example A habitat code of 18 and a management code of M1, would mean that the section is in agriculturally improved/ reseeded/ heavily fertilised grassland that is grazed by livestock. Also you can have several codes for the same section. The following tables are the descriptions of the habitat and management that are applied to the different sections of the transect.
The tables below the photographs of some butterflies shows the grid references and overall habitat description and codes for the transect.

The results of this transect are sent away to the butterfly conservation transect co-ordinator for Devon at the end of every recording year.  The results are then placed on the BC data base, which is then used to study varying distribution patterns, habitat management prescriptions and also can be used in the creation of a new atlas for British butterflies.
