We got some car troubles (power steering oil leaking, in Norway this is not what you want, got it fixed in Finland on the way back...), I took some minor damage to tendons in my right knee for descending 1000 meters too fast (took about 3 hours). Then the weather changed from 22 degrees, sunny to 7 degrees, foggy and rainy, in a day. The locality we visited was in the early summer so many of the species mentioned were impossible to find. After this we decided to cut the trip short. Luckily we didn't initiate any rock slides over each other nor did the fog surprise us in the fell.
Butterflies and moths:
Of other insects, some Carabidae and a couple of Cerambycids are of interest (went too early for these...) ... Some of the other flying ones would be less favoured (read: Culicidae, Simuliidae, Ceratopogonidae (mosquitos, blackflies, sandflies)) (Only mosquitos present this early in the season, quite pleasant)
(The big one I saw and missed due exhaustion was probably Xestia lyngei (Noctuidae, NT))
Other ones on the non-wishlist are Epirrita (LC, which is somewhat funny) and Operophtera (LC, which also has the potential to cause a little concern), but I strongly suspect these are present somewhere along the way (yes, there they were).
Overall, a fine, succesful and enjoyable trip, though a bit short and the roughness of the terrain was a bit too much. Trying to top the fell from the south did it I guess. More planning should be involved (we didn't know what the name of the fell was until we were back... we didn't have an accurate map... and I need a new compass). Thinking of going again, but the next trip should be later in the summer (mid-July) to avoid the snow still present this time of year (at altitudes of over 900 meters on all slopes but the southern one). Posting some photos in a few days.
