Male. Classic.

Male. Another colorless underwing that at first made me all excited, hoping that I finally found a different blue on the island.

Male. Worn, why the underside is very faded and probably why the body is lacking hairs.

The faded appearance could be why the species-diagnostic black spot in the Cell, underside hindwing, is absent, rather than the animal being of a true variant.

Male. Weakly marked individual, as many have been lately. The Cell spot on the forewing is barely visible and no orange spots at all.

Speculating if the little rain we've had during the summer and now a high pressure which has brought 30 degrees C to Denmark, continuing a week at least, has had any influence on the health of the population on Amager, making them weaker than usual?

Female. Looks like a piece of both forewings is missing in symmetrical positions making me wonder if it has been attacked by something, taking a bite..?

Female. Fresh and typical. As much of it you can see. Perhaps the same as 423.

Female. Perhaps this one is the same as 422. Freshly looking individual.

Female. Extremely worn, showing almost no traces of markings on the underwing. Fair to id it as this, simply because it is the only expected blue in the area.

Ellevehøj-sporet. A few early animals flying around. Here a male without the spot proximally in the cell of the underside of the forewing. Interesting to see the underside shining through in picture 1.

Imago. Female. A worn example. It looks like the females at this time of year are very small and very dark on Amager. Not something you can see here, but I've noticed it when driving around. Most individuals are seen along the dike in the scarce and short vegetation.

Imago. Male. Ehv sporet.

Was flying with normal looking individuals, but stood out with the almost turquoise tone above and certainly by the faintly colored underside. The forewing cell spot is barely visible.

Not so big a color difference to the undersides. However, the female normally being the darker one, is the lower one.
