My first butterfly of the year has emerged in the garden, a small tortoiseshell (neslesommerfugl), seen on one of the last winter aconites (vinterblom). I was surprised to see that someone saw a red admiral butterfly yesterday in Steinkjer, 75 km north of here. This must surely be an individual that has overwintered…the furthest north this has happened as far as I can see!
During summer 1998 I found this poplar hawk-moth / ospesvermer (Laothoe populi) on a ragged jack kale plant in my garden…this is the one and only time I’ve seen this species. I was reminded of this as a FB friend reported that there have been several sightings this year!
One of the worst invasions of diamond back moth / kålmøll happened a couple of days ago….here is a video showing hundredds swarming over one of my Lily White sea kale plants which is about to flower. Luckily they never do much damage to sea kale (Crambe maritima) as the harvest is over before they arrive, one of the big advantages of perennial brassica…on the other hand, annual brassica crops are being planted now in my area…they have little chance against these tiny moths….
I blame the rapeseed oil industry for this…they don’t overwinter here, but they migrate passively on warm winds from central Europe and Russia, even reaching Svalbard and Northern Norway…
The common hawker /vanlig øyestikker (Aeshna juncea) is a common dragonfly found from Ireland to Japan and in northern North America. This one (a female) “appeared” in my wheelbarrow when I was moving compost today!
