Many photos were taken on the Teverener heide. The best way to explore the Teverener Heide is on one of the four signposted circular walks. You will find the starting points and information boards at the Grotenrath, Scherpenseel and Hohenbusch car parks. In addition, a route marked with posts with white bands connects the three sub-areas of this nature park.

Explanation of the names of the
wings.
Azure damselfly.
33-35 mm. Male: lighter and more extensive blue than other damselflies. The black drawing is not connected to the back edge. The middle part of the abdomen appears very blue, with a regular pattern of black spots. On the side of the abdomen, the black spots run in a narrow stripe towards the front edge of the segments. Shoulder stripes normally developed.
Female: light areas green to blue. Usually with (almost) completely dark back of the abdomen. There is also a form with blue spots.
Blood red darter
34-39 mm. Legs completely black. There is a small yellow spot in the base of the wings
Male: Rear abdomen with black stripes, sometimes connected. Colored males have a blood red abdomen, a fairly even reddish brown breast, reddish brown eyes and a red face. Young males look like females.
Female: abdomen and forehead yellow, later brown. Rear abdomen in side view with black stripes, sometimes forming a black line. In old females, the underside of the abdomen becomes gray-dusted.
Flight time is from the end of May to the end of October, with a peak from mid-July to the beginning of September.

Male
Brown Damselfly.
34-39 mm. Light brown body, with dark bronze colored markings on the back of the abdomen and thorax (in young dragonflies with a green shine). The dark figures on the abdomen are torpedo-shaped. In the spring often much darker colored. The eyes often have a blue color. Pterostigmas long and brown and placed closer to the apex in the forewings than in the hindwings. At rest, all four wings are held together on one side of the body. The dark stripes on the thorax back have a straight underside. The dark stripe on the side of the bust (below the shoulder seam) is relatively wide.
They are mainly active from the beginning of April to the end of June, with a peak in late April / early May. On sunny days, however, active images can be seen even earlier in the spring, or even in the winter.

Coral damselfly.
25-35 mm. Legs light red. Chestpiece on top bronze-colored. Shoulder stripes very narrow or absent. No back eye spots.
Male: abdomen completely blood red. Eyes red. Pterostigmas dark red.
Female: three shapes can be distinguished based on the color of the abdomen:
1. Form erythrogastrum is very similar to the male due to a completely red abdomen. Only the segment edges are dark.
2. Form intermedium concerns all kinds of transitional forms between erythrogastrum and typica.
3. Form melanogastrum has a completely dark colored abdomen.
The flight time is from the end of May to the end of September, flight peak in the second half of July and the first of August.
Common sand-dragon.
44-50 mm. The abdomen is arrow-shaped: it starts broad, ends in a point and has straight sides. The face is yellow to brown. The pterostigmas are black.
Male: colored males have a blue-frosted abdomen with a distinct black tip. There are yellow stripes on the outer edges of the segments, which disappear in old males under even more blue frosting. The brisket is brown, without blue frosting. Young males that have not yet matured on the abdomen look like females.
Female: ground color of the body (abdomen, breastpiece and face) yellow. There are two thick black longitudinal stripes on the top of the abdomen.
Flight time is early May to late September, with the highest numbers in June, July and the first half of August.

Male
Great imperial dragonfly.
64-84 mm. Largest representative of the glaziers family. Breastpiece almost unicolor green. Drawing on forehead consisting of a black pentagon and black stripe, with a blue line in between.
Male: abdomen sky blue with black longitudinal stripe. Eyes green with blue tint.
Female: abdomen green (sometimes pale blue), with a broad dark brown longitudinal stripe. In young females, the green color on the breastpiece and abdomen can turn brownish. Eyes green, often with a brown tint.
Flight time is from mid-May to the end of October, highest numbers from mid-June to the end of August.
Male
Fire dragonfly.
36-45 mm. Fairly broadly built dragonfly, with an orange spot in the base of the rear wings. Pterostigmas large and yellow with black edge veins.
Male: brownish-yellow after hatching, with light shoulder stripes, a light stripe across the center of the thorax back and usually a thin black line across the center of the abdomen. However, colored males are largely deep red. Face, thorax, legs, abdomen and anterior wing veins: everything is red. Eyes dark red with blue underside.
Female: as a young female, not reddish. Old females turn a pale brown.
Flight time is from early May to early October, peak from mid-June to early August.

Male
Meadow Damselfly.
Length: 45-48 mm. Large damselflies with broad wings and a dense network of wing veins.
Males: blue shiny metallic body. Large black spot in wings (from knot to just below top). Wing veins with blue gloss. No pterostigmas. The underside of the abdomen tip is colored dirty white.
Females: green shiny metallic body. Wings uniform in color, green to green-brown tint. White pterostigma, in which wing veins run through ('pseudopterostigma').
Flight time from the beginning of May to September, highest densities from mid-June to the end of July.

Four-spot.
Length: 40-48 mm. Dragonflies with a fairly wide abdomen that tapers and ends in a point. Males and females are drawn similarly. Hind wings with a dark spot in the base. The veins in the dark spots are a striking yellow. Halfway the leading edges of the wings there is a dark spot, which is not found in other dragonfly species. Some specimens have an extra dark smear in the wings at these spots, and at the pterostigmas (form praenubila). The abdomen of young animals is predominantly orange with a contrasting black tip. The segment edges have yellow hems. Older animals turn dark brown with a gray tinge, the black point no longer forms a contrast. Noticeable air bubbles are often visible in the abdomen. Eyes reddish brown. Face cream, sometimes almost white.
Flat-bellied.
Length: 39-48 mm. Large dragonfly, which looks extra large because of the very wide abdomen. Both forewings and hindwings at the base with dark spot. The veins in the dark spots are a striking yellow. Shoulders with cream colored stripe. Male: abdomen after hatching orange, with yellow hems on the segment edges. After some time, the abdomen becomes blue frosted, with only the yellow hems along the segment edges remaining. In old males, the yellow hems also disappear under the blue frosting, making the abdomen completely blue. Female: abdomen after hatching similar to male: orange with yellow hems along the segment margins. In colored females the orange is discolored to brown, while the yellow seams remain visible. Very old females may show some blue ripening on the abdomen, but seldom as extensively as in the male. Females and young males: prominent air bubbles are often visible in the abdomen.

Puddle bolt.
Length: 45-50mm, Wingspan of 60-700mm. The colorless rear wings are angular at the base of the males and round at the base of the females. The blue-green eyes do not touch, as with the other dragonflies. The breast is yellow-green, with very narrow stripes and the yellow legs are also black striped.
The pond hull is, like all rhombus, bound to flowing waters, canals and large lakes with a sandy bottom.
