Bug Year 2023

My interest in bugs remains focused on butter, dragon, and damselflies although any large day flying moth will also be noted. I do however remain committed to not getting a light trap and getting any more into moths 😉

2023 was a good year for butterflies. I noted 61 species with 4 being new and taking my Norway list to 71, of, I believe, 100 possible species. The new species were Northern Wall Brown (bergringvinge), Northern Grizzled Skipper (moltesmyger), Frigga’s Fritillary (friggs perlemorvinge) and Northern Grizzled Skipper (moltesmyger). In addition I finally saw Poplar Admiral (ospesommerfugl) well enough to take pictures meaning I now have photos of all the species I have seen in Norway.  I have now seen pretty much everything I could expect to just bump into so will need to make more specific butterfly trips. I still have plenty of northern species to get and at least three of these are still possible in day tips from the cabin in Bodø and there are at least five species which I should be able to get easily enough less than an hour’s drive from Oslo: Essex Skipper (timoteismyger), Scarce Heath (heroringvinge), False Heath Fritillary (mørk rutevinge), Meadow Brown (rappringvinge) and Chequered Skipper (gulflekksmyger).

I must admit that my interest in odonata wained during the year. I think this is because damselflies at least can be quite hard work and that I have also seen pretty much all I can expect around Oslo without making specific trips. I did add three species though taking my Norway list to 33 species of a possible 52 - Subarctic Darner (torvmoselibelle) gave itself up when I checked a suitable bog in Maridalen (and was able to get good enough pictures), White-legged Damselfly (fjærbeinvannymfe) when we walked along a suitable river near the cabin at Hulvik and Lilypad Whiteface (vannliljetorvlibelle) which required a specific trip to the only known site in Oslo.

My first butterfly in 2023 was on 8 April so only 12 weeks or so until my next blog post that includes a bug.

Pictures of my new species first and then some other random shots that I like

Purple Sandpipers 2024

Today we have had a mini heat wave in Oslo which rather surprisingly arrived on the back of northerly winds. From temperatures in Maridalen of -27C less than a week ago the thermometer showed +5C today! Interestingly it was also warmer the higher up one came. We will return to below zero tomorrow and after forecast to once again have double digit minus next week.

I paid a visit to Huk, Bygdøy early in the morning and was entertained by the flock of overwintering Purple Sandpipers running around on the frozen rocks nearly at my feet. On the sea there was more variety than my last visit with Shag, Little Auk, Razorbill, Guillemot and both scoters.

Maridalen gave a duo with Pygmy Owl being the missing trio member.


Purple Sandpiper (fjæreplytt), 1 of 9 I saw








the rocks on the shore above the high water line were all covered in ice

I am seeing the Great Grey Shrike (varsler) in Maridalen far less often but when I do see it it is always in the same area. With all the snow it must be difficult for it to find food


Grey-headed Woodpecker (gråspett)

Beardies

If you can withstand the cold then it is fantastic to be out at the moment with blue skies and no wind. It is slightly warmer now with temperatures staying above -20C and we are forecast to have a brief period with plus temperatures on Thursday before it gets cold again.

There are still very few birds to see though and a long walk in the forest today in perfect listening conditions was very poorly rewarded although I did hear my first Black Woodpecker and Hazel Grouse of 2024. I also finally had a Pygmy Owl in Maridalen and with both Great Grey Shrike and Grey-headed Woodpecker yesterday then the trio of interesting birds remains.

A visit to Fornebu yesterday gave fantastic views of the Bearded Tits but again Wrens were absent and it wouldn't surprise me now if I don't see or hear one until the spring,

the Bearded Tits (skjeggmeis) were feeding on the edge of the reedbed and often went into bushes





this female had darks stipes on its back








here she has been eating snow



Grey-headed Woodpecker (gråspett)

in addition to the red feathers there is a piece of peanut skin on her crown





Pygmy Owl (spurveugle) and an angry Coal Tit (svartmeis)

a Lesser Spotted Woodpecker (dvergspett) was a welcome sight in Maridalen
