[Note Guidelines] Photographer's Note
This part of the Jćren coast in southwest Norway is a botanist's delight. The coast-line offers marine life, heathland flora and fauna and wetlands all within a very short walking distance. The photo shows an insect, possibly a hoverfly, trapped in the sticky leaves of Drosera rotundifolia. I think there is also a flower spike here as well, and I shall check within the week, as I have not seen it flowering before. The sticky leaves are approximately 5-7 mm in length.

Drosera, commonly known as the sundews, comprise one of the largest genera of carnivorous plants. The members of the family Droseraceae lure, capture, and digest insects, (as shown), using stalked mucilaginous glands covering their leaf surface. The insects are used to supplement the poor mineral nutrition that sundews are able to obtain from the soil in which they grow.

Insects, are attracted by the sweet secretions of the peduncular glands. Upon touching these, the prey become entrapped by sticky mucilage which prevents their progress or escape. Eventually, the prey either succumb to death through exhaustion or through asphyxiation as the mucilage envelops them and clogs their spiracles. Death usually occurs within one quarter of an hour.

Habitat: This Drosera is growing in association with sphagnum moss, (shown here), which absorbs much of the soil's nutrient supply and also acidifies the soil, making nutrients less available to plant life. This allows the sundew, which doesn't rely on soil-bound nutrients, to flourish where more dominating vegetation would usually out-compete them.

Scientific classification:
Kingdom: Plantae
(unranked): Angiosperms
(unranked): Eudicots
(unranked): Core eudicots
Order: Caryophyllales
Family: Droseraceae
Genus: Drosera

Hallo Amelia
What a sheer delight it is so look and appreciate this stunning Drosera on my computer screen. I am sure the place where you photographed this vivid beauty is not only a delight to any Botanist but just as well to any photographer. You do mention that insects are attracted to this plant and therefore one will not just be able to photograph the beautiful plants but also the insects that I am sure will be plenty of. Thanks for sharing this pretty flower that is nice and sharp and presented in a lovely manner. Best regards.

Nice shot of this drosera, so fine details, so hard to capture.

Thanx for the comment, just read your profile, you've lived in two of the wildest places in europe, loved scotland on my visit, and the first trips to sweden promise much for the rest of scandnavia.. Maybe a longer trip in a couple of years. Here in sweden most are Dactylorhiza incarnata and traunsteineri in such wet places..I expect Norway to be similar,

cheers

Nice view and the lighting allows the dramatic expression well documented.

What a cool plant! My daughter and I worked on a science project together on carnivorous plants, we were considering this species but eventually worked with the flytrap species. Very nice macro image the details and colors are very exciting. :)
