09-07-2022 - Butterflies on the Sint-Pietersberg

It is very quiet in the Netherlands in terms of birdlife and Maartje wanted to see the Marbled Fritillary that was still missing on her butterfly list. Alwin also missed this one and he also missed a Marbled White. Both butterflies were on the Sint-Pietersberg and so it was agreed to spend a day on the hill. I'm not such a butterfly twitcher but I really like photographing these critters.

At 8 o'clock in the morning Alwin picked us up in Uden. It was still a bit cloudy but that would go away. For butterflies you need a lot of sun. Right on time we arrived at the Sint-Pietersberg and there weren't many people looking for butterflies yet. The first target type was the Marbled White.

We started looking and suddenly heard a Frisian sound; "hjir is hy". We looked back and saw the familiar faces of Andries Zijlstra, Hetty Sinnema, Marcel Stienstra, Alwin van Lubeck and Rik Wever. They had found the Marbled White. The butterfly was easy to see and nice to photograph.

The first target species was in. We continued our search and quickly spotted several species of butterflies. A Dingy Skipper was found by Alwin, a rare butterfly. It was swarming with Common Blues which are more common. I kept me busy with photographing a Banded Demoiselle and a Black-tailed Skimmer. Maartje kept watch at the many butterfly bushes. She pointed me to a number of Comma Butterflies that could be photographed. 2 Great Tits had also found the butterflies and feasted on them.

We suddenly heard someone yell "Marbled Fritillary" and walked in the direction of the sound. At a large butterfly bush, we did indeed see a Fritillary butterfly that eventually turned out to be an Silver-washed Fritillary. That is of course not wrong. The Silver-washed Fritillary was gratefully photographed. Alwin found not much later a rare Mazarine Blue.

A White-letter Hairstreak was found and photographed. I heard that a Wall Brown had been seen further up and I hadn't photographed this one yet. The butterfly was quickly found and I even found 2 mating Wall Browns. Couple of Holly Blues were also seen here. Alwin and Maartje suddenly saw a Marbled Fritillary. They called me but the beast had already disappeared. Because Alwin and Maartje were not 100% sure, this was not noted. A Clouded Yellow posed nicely for the camera. We also found the rare Southern Skimmer here.

We decided to look higher up and chose the hiking trail that led to a plateau on the Sint-Pietersberg. En route we saw 2 Map Butterflies. On the plateau, Arend Vermaat drew our attention to a Mallow Skipper another target species. We searched further and found a female and male Southern Skimmer.

We went back to the car and on the way we saw many Wood Whites. Suddenly I saw a Marbled Fritillary. This time it was undoubtedly a Marbled Fritillary. He was fun to watch and photograph. Maartje was happy with her new butterfly species. On the same piece we also found a Short-tailed Blue.

On the way down we found a Dingy Skipper and a Brimstone. A little butterfly turned out to be a to be a Latticed Heath, a moth. A Brown Argus was nicely photographed and this also applies to a Speckled Wood.

It turned out to be a very successful day with no less than 27 butterfly species! Many new to me. I was very happy with the pictures taken. The combination of the Canon R3 with the 100-500 lens works fine for this type of photography. Once back in Uden, the BBQ was lit and we enjoyed an ice cold beer. Butterflies and dragonflies are actually quiet nice.
