Chrysidid reflectance measurements

[Alex]

Hello everyone!

I did some reflectance measurements on a few of my collected Chrysidids (also included are some beetles) this week for a small course project, and I just finished the graphs. Thought I might as well post the figures here if anyone is interested.
Methods:
Used a full-spectrum light source focused by a light-guide onto different parts of the insect, and another light guide to collect the light and send it to a spectrometer. The spectrometer was calibrated against a full spectrum (white) reflecting surface. The spikes that are visible in some graphs (often around 480nm and 520-530nm) are electronic noise that I unfortunately couldn't get rid of. All the graphs show relative reflectance, so that the highest value in the 300-800 nm range is set to 1.

The file names indicate which species, sex (in some cases) and part of the specimen that were measured:
S/T = sternite/tergite, followed by their respective number.
Sternites/Tergites= Measurement could not be said to come from a specific segment.
Pronotum/Scutellum = just means the anterior and posterior halves of the thorax
Thorax = The whole of the thorax

Attached the files a .zip, since there is 34 graph pictures all in all.

Hi Alex,

thanks for these informations.
Very interesting.
Maybe there will be some applications, but I have to think about it.

Thanks for now.
