Additional Information
en: Caterpillar (larval stage) of Cydalima perspectalis or box tree moth.
- This side view shows how it devours box tree leaflets in almost perfect semi-circles.
- The close-up reveals the mouth organs, the thoracic legs, and the tiny eye. The partially transparent rear section of the body displays branching vessels and fibres.
- This caterpillar specimen was alive throughout the series of shots and continuously kept feeding.
- It is a non-native species introduced to Europe after the year 2000.
- Length of black caterpillar head from mandibles to neck: approx. 2,6 mm, resulting in a magnification ratio of approx. 2.0x as compared to full format.
- Image taken at location: Aplerbecker Mark, Aplerbeck, Dortmund, Germany on May 30th, 2019.
- See below for technical details concerning the "making of" this image.

- Die Seitenansicht zeigt, wie die Raupe das Blatt in nahezu perfekter Kreisform frisst.
- Diese Nahaufnahme zeigt die Mundwerkzeuge, die 3 Vorderbeinpaare sowie das winzige Auge. Im teilweise transparenten Hinterteil sind einige verzweigte Gefäße und Fasern sichtbar.
- Die Raupe wurde am Leben gehalten und fraß während der Aufnahmeserie ununterbrochen.
- Der Buchsbaumzünsler stammt aus Ostasien und wurde kurz nachdem dem Jahre 2000 in Europa als invasive Spezies entdeckt.
- Länge des schwarzen Raupenkopfs von den Beißwerkzeugen bis zum Nacken: 2,6 mm. Vergrößerung gegenüber Vollformat circa. 2,0x.

Technical Details / Making of this Image
- NOTE: This image was taken on a full frame sensor at a calculated magnification ratio of 1:1.6 (0.63x) in order to retain sufficient depth of focus, explicitly including the bristles.
- This roughly square crop focusses on its mandibles, its finely detailed body, and the clipped leaf edge at a magnification ratio of approx. 2.0x.
- The TTL flash was set to -1.0 apertures in manual mode. This prevented over-exposion of the highlights. The brightness level of the all other areas being compensated for during RAW processing.
en:
- [4] Camera / lens settings: 16-bit RAW (.ARW): [0] Flash TTL, exp:-1.0.
- [5] Flash settings: The TTL flash spreader was set to -1.0 exp. to reduce over-exposure artifacts and was then compensated during raw image processing by enhancing the exposure level appropriately.
- [6] Adobe Lightroom: imported .RAF file (a) applied preset 002 (Presence+Sharp+NoiseRed) (b) Subsequent changes (final values stated): Exposure now:+2.05; whites-20 (c) altered mode to "LAB mode", set Hue: Y+10; Sat O+10, Gr+10; Lum Gr+20.
- [8] Adobe Photoshop: (a) removed sensor spots (b) cropped (c) saved as .PSD file (d) exported as 8-bit/JPG file.
