Camptogramma bilineata

Posted by
Johan Dierckx (Wijnegem, Belgium) on 21 July 2010 in Animal & Insect and Portfolio.

Camptogramma bilineata (Yellow Shell / Gestreeptje goudspanner) is a moth of the family Geometridae. The name "Geometridae" ultimately derives from Latin geometra from Greek γεωμέτρης ("geometer, earth-measurer"). This refers to the means of locomotion of the larvae or caterpillars, which lack the prolegs of other Lepidopteran caterpillars in the middle portion of the body, with only two or three pairs at each end. Equipped with appendages at both ends of the body, a caterpillar will clasp with its front legs and draw up the hind end, then clasp with the hind end (prolegs) and reach out for a new front attachment - creating the impression that it is measuring its journey. In Belgium the species is not very rare but like most of the moths they keep hiding in the vegetation during the day and so not easy to find.

@Julie: Thank you very much, Julie.

Great backlighting on the fern. Was the moth hiding? The movement you described for the caterpillar sounds like what are commonly called 'inch worms' in North America.

@Julie Brown: This moth was indeed hiding at the underside of the fernleave. I only could find it after carefully searching through the "fern-wood". I know there are several species hiding there during the day but they are all diffucult to find without disturbing them. Once they are disturbed and fly away, it is almost impossible to relocate these tiny moths because they nearly always search a new resting place at the undersides of the fernlaeves. I think the term "inch worms" suits the movement very well. On Wikipedia I could find "Inchworms are the caterpillars of geometer moths." so we are talking about the same ... :-) Have a nice day, Julie.

Veronique from Sarrouilles, France

superb light and the leaves are gorgeous

@Veronique: Thank you very much, Veronique. I was focussed more on capturing the moth but the fernleaves were a nice bonus :-)

Mascha from Kootstertille, Netherlands

Heb je de varens ook zonder vlinder genomen? Die zijn prachtig, zeker met dit licht worden alle details zichtbaar. Ik vind zowel de vlinder als de varens mooi, maar bijelkaar te druk.

@Mascha: Ik heb inderdaad een aantal pogingen gedaan om de varens ook afzonderlijk in beeld te brengen in tegenlicht, maar de opnames vallen me eigenlijk nogal tegen. (Of misschien had ik er teveel van verwacht). Je hebt wel een punt over de drukte van de combinatie van patronen en structuren, maar de vlinder zat nu eenmaal op die plek en de soort kom ik (helaas) niet elke dag tegen... Ik laat de vlinder ook liefst zo ongestoord mogelijk zitten. Van collega-fotografen hoor ik wel eens praten over praktijken als het vangen van (nacht)vlinders, ze een tijdje in de koelbox steken, om ze dan nadien op een mooi (lees - ideaal foto-) plekje weer uit te zetten.. ze zijn dan wat rustiger en poseren tot ze weer voldoende opgewarmd zijn ... Dat soort praktijken doe ik liever niet aan mee. Is de vlinder gevlogen heb ik gewoon pech gehad.

'Hangend aan een vliegengordijntje'.......;-) Prachtige lichtval, Johan!

@♏arleen: Weer tijdens het "gouden uurtje" genomen... Beetje jammer dat de vlinder onderaan de varen in de schaduw zat (maar wie kan hem dit kwalijk nemen bij de warme temperaturen van afgelopen periode) wat de belichting wel heel moeilijk maakte. Misschien gaat in deze foto de aandacht toch iets te veel naar de varenblaadjes dan naar de vlinder ?

Loner from Wörgl, Austria

Wunderschön - daß es überhaupt möglich ist, so viele Details trotz oder wegen des Gegenlichts festzuhalten.

25 Jul 2010 7:38pm

@Loner: I'm glad you like this one. I was wearing a (nearly) white shirt which acted as a kind of reflector for the sunlight on the moth... I think that is probably why you can still see the details in the wings...

Dutçh from Chicagoland, United States

I really like how you've captured the light though the foliage to illuminate the specimen yet have given the photo with that same curtain a very intimate, private feeling.

25 Jul 2010 9:35pm

@Dutçh: I think I don't understand what you want to say :( Can you explain in a different way ?

Monique from Koh Samui, Thailand

Heel sfeervol en de mooi belichte blaadjes geven hier een extra dimensie aan, heel creatief en ik vind de combinatie erg mooi.

27 Jul 2010 12:08pm

@Monique: Er waren wat verschillende meningen over de achtergrond. Over smaak kan je nu eenmaal moeilijk redetwisten. Voor mij geeft de foto weer hoe de vlinder zich weet te verstoppen in de (varen-)vegetatie en krijgt zo ook een ecologisch effectje mee - zo eens iets anders dan een puur portretje...

Dutçh from Chicagoland, United States

I'm sorry I was not clear. You had mentioned it is hard to find this species, they hide themselves, clearly you have depicted that here in the way that the leaves almost shield the butterfly from view. Yet.. the light shining through the leaves manages to bring warmth to the picture, a magic in how each leaf is defined.. and intimacy as if we are looking into something magical, special and secret. I hope that explains my thoughts better.

28 Jul 2010 5:11am

@Dutçh: Now I understand :-) Thanks. And I agree on your opinion on this. For me capturing the species was the first concern while taking the image, but it has indeed a kind of intimacy this way. Nice analysis :-)

Krisu from Tampere, Finland

Excellent! the light is so beautiful!
