Yellow on the legs and black line down the eye. Not sure if the prominent two white lines on the thorax, and the likewise Y at the back of it, can indicate a female or a young individual.

The prominent vulvar scale (skedeklap) below S9 makes it a female.

Probably a young with the pale colors, including extensive yellow on the legs.

The vulvar scale (skedeklappen) apparently is flexible being able to retract and expand changing the size of the visible part. Notice the size difference in photo 3 and 4.

The moustache is probably a bit more blurry down the side of the frons on this individual than normally seen, but still good for the species. Which is also supported by extensive yellow on the legs, the incomplete black rectangle on the side of the thorax plus the rather vertical vulvar scale. Only one seen today.

I think the shape of the black moustache and the amount of yellow on the forelegs go better with this species than striolatum [Stor Hedelibel].

The vulvar scale guarantees the identification. Otherwise a good example of how important it can be to have more photos of a subject when claiming a certain species. Here the moustache looks almost non-existing down the side of the eye in the frontal view and abnormally large in the lateral view.

Imago ♂

Has grabbed a sangineum [Blodrød Hedelibel] female showing the all-black legs, pointed moustache and bright colored side of thorax with limited black lines.

It's an old male and the amount of yellow on the legs appears more restricted than it would have on a younger male. One might even suggest that it is a striolatum [Stor Hedelibel] instead of, also showing a not-so-protruding moustache as might have been expected on vulgatum. But I think it looks this way because of the age and the difficult angle to judge from. Normally, on striolatum, the yellow ovals on the side of the thorax are more conspicuous than is seen here, where they seem to fit vulgatum well. Another point in favor of vulgatum is the simple fact that striolatum is normally not seen here...

Mature. Another example of photo-misguiding if not sufficient material to id properly. Looking at the face-on in photo 1 the moustache is limited like one would expect it to be on striolatum [Stor Hedelibel], but becomes obviously vulgatum-like in photo 2-3. The species is also supported by the large vulvar scale and much yellow on the legs.

The moustache is good for the species as is a good amount of yellow on the legs. And the side of the thorax is uniformly colored compared to what is normally seen on striolatum [Stor Hedelibel].

You can discuss whether the moustache and the amount of yellow on the legs would fit a striolatum [Stor Hedelibel] better, but the shape and size of the vulvar scale should eliminate all doubt in favor of vulgatum, and again, making it clear that photo id often is not as straight forward as one might wish for.

As far as I can tell, the two photos, (1, 2-3) show the same animal, with the cut off half of the left foreleg. However, the first photo was taken near the southern narrow bridge over the channel along Ellevehøjvej, and the other one I took 5 minutes later east of the southern bunker area, some hundred meters away. Am I wrong or did it follow me there?

Next part is to accept the species. The moustache does not look too strong down the side of the eye, but it still seems to be a bit too strong and present to fit striolatum. Also there seem to be quite much yellow on the foreleg and the side of the thorax also look darker than normally seem on striolatum.
