Hi David, in answer to your question we managed a rather appalling 21 species on our Land's End to John O'Groats Honeymoon Walk. The species we saw were as follows:
Large Skipper - just a few
Brimstone - commonplace, adults and larva (although the species is absent from Scotland! No foodplant, you see)
Large White - commonly seen
Small White - commonly seen
Green-veined White - commonly seen, adults and larva
Orange-tip - frequent at first, larva only latterly
Purple Hairstreak - 1 larva seen
Common Blue - few and far between apart from parts of Scotland where more common
Holly Blue - common in Cornwall/Devon
Red Admiral - frequent, larva also found
Painted Lady - several individuals
Small Tortoiseshell - common in patches
Peacock - mostly larvae noted along with a few adults
Comma - infrequent
Small Pearl-bordered Fritillary - scattered in Scotland
Pearl-bordered Fritillary - a handful in Cornwall
Dark-green Fritillary - several in Scotland
Speckled Wood - commonplace
Wall Brown - common along Cornwall/Devon coastal areas
Scotch Argus - frequent in Scotland
Meadow Brown - infrequent
Small Heath - infrequent
Large Heath - a handful in northernmost Scotland
Ringlet - commonly encountered
Bearing in mind that, apart from the Cornwall/Devon heatwave, we only had a handful of sunny days for the entire duration of our trip we fared moderately well. But I honestly can't recall any other year where I've missed so many 'usual' species. For instance the only hairstreak ALL YEAR was the solitary Purple Hairstreak larva. The only skippers have been Large. No White Admirals, Purple Emperors, Chalkhill/Small/Adonis Blues. NO SMALL COPPER!!!!!! No Grayling, no Silver-washed Frits. Despite a stupendously memorable walk, this has been by far my worst ever summer for butterflies. Apart from the Monarch
The Justgiving site is still live, there's still time to donate to a very worthy cause if you so wish. Just follow the link under this post. We've raised over £4500 so far, more would be appreciated though!!
Cheers,
