20 km south, 40 years back

Today I took the car to the peninsula Vånören – ca 20 km linear distance, ca 35 with the car. I thought, I would experience a new place, but well, I just forgot, that I’ve been there already. Anyway, a nice place with quite different types of landscapes. Forests, shallow bogs, rocky coast, small lakes and big granite rocks.

When I came to a rock pool, I saw the first tadpoles of the year. I kneeled down and had a closer look. After a while I discovered other animals in the shallow and clear water – most of them insect larvas. Some of them I knew, others I had to look up when I was home again.

Here they come:

For an hour I was an eight year old boy again. A boy, that has been loving water and all the small animals in it. When I was a child I had tadpoles, water insects, newts or water snails in big plastic bathtubs in the garden each summer.

Back to present age: I kneeled on the rocks, looked at the tadpoles, the great diving beetle larvae (they look like small aliens) – and the shy caddisfly larvas in their self-made “burrows”.

The photos are not the best – the animals were under water, the camera over water. The refraction of the light made it hard to focus and many photos were blurred. But anyway, it was great fun (beside of the hurting knees kneeling on the rough rocky ground).

One question is still open. Have a look at the 5th photo. What is it?! It floated underwater, was round 15 mm long and almost transparent. I don’t think, it’s an insect, perhaps a fish larva, but I don’t have any clue. If you know, what it is, let me know.


Number 5 is a mosquito larva, not one of the biting ones, but probably of the family Chaoboridae. German wikipedia describes the larvae as Glasstäbchenlarven which means “glass rod larvae”. A good description in my opinion.

From winter to summer in seven days.

I hardly can remember the intense snow fall a week ago, when I look at a day as today.

Today in a nutshell: sun, shorts, temperatures between 15° and 22° C, sandals, blue sky, t-shirt only, ice cream.

It looked like early spring with only some of the birches starting to come into leaf but it felt more like high summer with today’s temperatures.

Annika and I have been in the “Arboretum Norr” today, just five days later as last year. Last year we could see many different species of flowers, this year only some, mostly Tussilago and Alpine Penny-cress, the two flowers that use to bloom first in the season. No wonder, April and May has been colder than last year. But today warmth attracted many butterflies, such as this European peacock.

And Tussilago is a beautiful flower anyway.

Vampires of the North

This article is part of the series “2017-07: Tromsø”.

It’s no secret, that blood-sucking vampires exist in Scandinavia. It’s another species then the half-human vampires known from countless fantasy novels and therefore there are some differences:

The bad part: They don’t dread the sunlight, they are countless and they can fly!

The good part: You won’t turn into a vampire yourself when they bite you, they are much smaller and they are easier to kill.

But sometimes you come too late to prevent the vampires attack …

This mosquito died in Miekojärvi between Överkalix and Övertorneå, where Annika and I stayed overnight on our tour to Tromsø.
