I have pinned two six spotted tiger beetles (Cicindela sexguttata), and I have noticed that they have changed from shiny green to shiny blue in a few days during the drying process. Does anyone know why this has occurred?

Lighter pigment as yellow decompose leaving the blue color behind.

I have collected lots of those and none have changed color. Were yours exposed to sunlight while drying?

I guess you are lucky, blue is rare in those. Do you have a picture?
Cheers

I have the same issue. Let me know if you figure it out. The blue cicindela can be outstanding.
Cheers

I'm unsure about luckiness of color changes. You can always (very easily) change color by exposing specimens to UV lights (or simply, sun), however, that's not the natural color of a specimen. If you are studying such light spectrum and colors of insects, may not be a great specimen to refer onto.
