Wing interference patterns (WIPs) in the banded mosquito Culiseta annulata (Schrank, 1776)

Summary[edit]

Description
Eesti: Alles hiljuti avastati, et mitmesuguste putukate läbipaistvad tiivad ilmutavad tumedal taustal ootamatult kirkaid struktuurseid värvimustreid (tiiva interferentsi mustrid). Tiivalt peegeldunud valguse lainepikkuse määravad tiiva kitiinse membraani paksus, pinna mikrostruktuurid (vaata suurel suurendusel), soonestus ja soomuste paigutus. Tiiva interferentsi mustrid kui liigi- ja sugupoolespetsiifilised visuaalsed paarumissignaalid võivad omada tähtsust mõnede putukate taksonisiseses suhtluses (Drosophila spp. jt). Küsimus, millist rolli mängivad tiiva liigispetsiifilised struktuurivärvid pistesääsklastel (Culicidae) alles vajab selgitamist. Fotol on kujutatud interferentsi värvilisi mustreid euroopa linnusääse Culiseta annulata (Schrank, 1776) läbipaistval tiival.

Pildil olev sääsk on püütud Eestist. Pildistamisel kasutati mikroskoopi Nikon Eclipse FN1, 20-kordse suurendusega objektiivi ja digikaamerat Nikon DS-Ri2 pinufoto meetodil. Umbes 70 osapinu kokku liitmiseks üheks pildiks kasutati pilditöötlusprogrammi Photoshop.

Pilt (pinufoto TIFF) on tehtud 18.11.2021. Pilt on lõigatud, ülisuure originaali resolutsioon on 41632 x 17530 pikslit.
English: Recently, it was discovered that various insects with seemingly transparent wings, display vivid structural coloration against dark backgrounds. Wavelength of the reflected light is dependent on the thickness of the chitinous membrane of the wing, microstructures (see at high magnification), hair and scale placement, and venation. In some insects (Drosophila sp.), WIPs may function as species- and sex-specific visual mating cues in a range of taxa. The role of species-specific WIPs in Culicidae mosquitoes is unknown.

About 70 small, partial focus stacked images across the mosquito wing were photomicrographed at 50X magnification with the Microscope Nikon Eclipse FN1 and digital camera Nikon DS-Ri2. These small image stacks were merged together using the image processing software Photoshop.

Image was taken on November 18, 2021. The image is a crop of the very large original image with the resolution of 41632 x 17530 pixels.
