Sympetrum pedemontanum - female

Posted by Johan Dierckx (Wijnegem, Belgium) on 11 August 2010 in Animal & Insect and Portfolio.

I showed a male specimen in yesterday's image so more info on the species can be found there. Females are yellowish or pale brown colored and the pterostigma is cream. Kristen asked in a comment on yesterday's image for more detail in the wings... so for todays female I chose a more wing-orientated image. Like most of the Sympetrum species wings are mostly held to the front while resting. That is why the focal plane runs from the eyes though the wings. Left and right wings seem a bit asymmetrical in this image. This optical effect is due to the wind, comming from the right, pushing the right wings a little to the inside. I observed this female for nearly an hour. She regularly flew away but always returned to exactly the same spot within a few minutes. So a tip for those who wants to make images of dragonflies: don't go chasing after them when they fly away - most of the time they are too fast. First observe, try to find their resting-spot and just wait for them to return... they (nearly) always do... It will save you some energy and meanwhile you have time to set up a tripod and prepare for a good image ...

Hallo, Johan ! Jetzt hast du auch noch das Weibchen der Gebänderten Heidelibelle fotografieren können. Ich gratuliere dir zu diesem Foto ! Ich habe mir heute den Füß gebrochen und kann leider in nächster Zeit vom Fotografieren nur träumen. LG Sonja

@Loner: Sonja, first of all, let me wish you a soon healing on your foot ! This is just one of the worst-case-scenario's for a nature-photographer. About these images: I was able to spend nearly the entire day within a population of this species so I had enough time to observe and make images to document the species. I was just lucky to find the population soon after I left the car. I think there were about 30 specimen flying in the neighbourhood of a nearly dried pool (hard to count the exact number). I even was able to make some images from the mating-wheel (copulation) and saw some females during ponderation (but to far away to make good images - should have needed a telescope then :-D ). For me such a day is ... holiday (or should I say "holy-day").
Hope you will recover very fast !!!

Julie Brown from Indianapolis, United States

Nice perspective here, Johan. It is difficult to get both the body and the wings sharp on dragonflies. Good advice about not chasing them.

@Julie Brown: Sharpness in an image is very relative I think. I think it is not nescessary to get the whole dragonfly, damselfly, butterfly, ... sharp (except for a determination book :-) )

Dutçh from Chicagoland, United States

It's wonderful! What are those little.. reflective areas on the wingtips? They seem to catch the sunlight and cast if off again. I saw some dragonflies on our last photowalk in July before my camera died. They were too far away and in the water to get detail but I did see this flash of light as their wings moved. I would guess this part of the wing is responsible for that? And.. thank you for posting this one too! :)

@Dutçh: "The little reflective areas on the wingtips" is called "pterostygma" (I referred to these a few times already in my descriptions). Wikipedia says: "The pterostigma is a cell in the outer wing of insects which is often thickened or coloured and so stands out from other cells. It is particularly noticeable in dragonflies, but present also in other insect groups, such as snakeflies, hymenopterans and megalopterans. The purpose of the pterostigma, being a heavier section of the wing in comparison to nearby sections, is to assist in gliding. Without the pterostigma, self-exciting vibrations would set in on the wing after a certain critical speed, making gliding impossible." - I can't explain better (certainly not in English). The color of the pterostygma is often a diagnostic feature for dragonflies and damselflies but be carefull: young specimen hava not full colored pterostygmata, so mostly they are white or creamy, but some adult species show this color too.

love the flash of light on the wings

@Skyriani: Light is always the prominent element in an image ... so I pay much attention to that.

wow
