Erythromma najas

Posted by
Johan Dierckx (Wijnegem, Belgium) on 30 June 2010 in Animal & Insect and Portfolio.

Erythromma najas (Red-eyed Damselfly / Grote roodoogjuffer) is a member of the damselfly family Coenagrionidae. Lenght is about 30 - 36 mm Damselflies are similar to dragonflies, but the adults can be differentiated by the fact that the wings of most damselflies are held along, and parallel to, the body when at rest. Furthermore, the hindwing of the damselfly is essentially similar to the forewing, while the hindwing of the dragonfly broadens near the base, caudal to the connecting point at the body. Damselflies are also usually smaller, weaker fliers than dragonflies, and their eyes are separated.

En ze lijken ook vaker te worden opgepeuzeld door kikkers dan een libel.....
Prachtig verticaal beeld en zo apart deze twee verschillend gekleurden!

@♏arleen: Het is vaak zo bij juffertjes dat de vrouwtjes en de mannetjes een ander kleurpatroon hebben. Mannetjes hebben over het algemeen meer blauw, vrouwtjes zijn over het algemeen meer naar de groene kant. Paringstandems zijn niet zo gek moeilijk te vinden ... het lijkt soms of deze diertjes niet veel anders doen :-)

Nice behavior captured here, Johan. It is interesting that the female? has a green body.

@Julie Brown: The female is indeed the green one. In almost all odonata the males and females have different colors...

Très belle photo macro vue de profil.
Je te félicite pour cette prise de vue.
Bonne journée à toi.

@Jean-Michel: Merci beaucoup, Jean-Michel. Bonne journée aussi.

Naar dit standje ben ik nog steeds op zoek ;) Erg mooi met de diagonale lijnen en de schitterende kleuren van de juffertjes! Persoonlijk vind ik 't contrast wat hard voor zo'n mooie foto, maar dat is een kwestie van smaak.

@Monique: De foto is niet in al te beste lichtomstandigheden genomen. Rond het middaguur en dus erg hard licht, vandaar wellicht de te hoge contrasten. Maar dit "standje" kon ik toch ook niet weerstaan ;-)

Dutçh from Chicagoland, United States

With all these bugs I might think you are infested over there.. itch scratch! You captured these guys really well!

@Dutçh: I'm not sure I understand "infested" the proper way. It's like an invasion of species?

Dutçh from Chicagoland, United States

Yes I was just teasing or joking with you that you have a lot of bugs there. Really you take wonderful photos of them and I have tried and failed.. thus you have more bugs than I do :)

@Dutçh: the trick : be patient :p

daniela scharnowski from Berlin, Germany

Harsh light and it looks a bit oversharpened but caught-so-well-in-the-act ;D

@daniela scharnowski: Hehe, the last one of an extensive comment-flow from you... Thanks for that !!! I know the light was not good: midday... but the action just cought my eye :-). About the sharpening... just did the same as always - don't know what went wrong - can't get it better.

daniela scharnowski from Berlin, Germany

Maybe i got that impression from the harsh contrast due to the light - never mind ;P

10 Jul 2010 7:22am

@daniela scharnowski: I agree. Think the oversharpened impression is due to the harsh light. I do mind :p Makes me more convinced of taking pictures only in good light ...

daniela scharnowski from Berlin, Germany

Don´t you have a diffusor? I used that often in that kind of light - since insects love to sit still aroung midday ;D

12 Jul 2010 6:53am

@daniela scharnowski: I have one, but most of the time I have a hand short. How do you manage to hold a diffusor in the right place, holding your camera focussing and pressing the button at the same time ? All tips welcome :-)

daniela scharnowski from Berlin, Germany

It depends on the shot, with the Panasonic and the diopter i have a small working distance (between 20-40 cm) and this range i can cover with my arm - with that camera I also rely on the autofocus.
with my pentax and some manual lenses it gets more difficult, true, but sometimes i can simply jam that diffusor (or reflector also) in the bushes and it may work - it always depends on the environment... if that all doesn´t work I simply put down the EV to -2/3.....

13 Jul 2010 5:13pm

@daniela scharnowski: I once made a whole constuction to be able to put it right above without holding it in hands. But this is not very practical to carry around all the time. So I mostly work without . My macro shots are almost never with AF so I need my hands to focus ... But thanks for the tips, Daniela.
