You are absolutely right! It’s BANDIT. I will change my observation reference!
(Something tells me you are into IDing)
Thanks for the catch
Bandit, being an archaeologist, would NOT have made this error, I’m certain.

I have a lot of these… Beginning with:
We have blue Condylostylus here, which @zdanko and others have identified as a newly described species, C. purpureus.
And of course there are the bluets and Blue-Eyed Ensign Wasps and such, but my favorite bit of blue is the startling tail on this species indeterminate Condylostylus I saw some three years ago, the only one like this I have seen. I love these pretty flies so much; they are like little flying jewels and seeing a new-to-me one feels amazing.
Not newly described; rather, it was recently discovered to have been introduced to Florida.
I’ll add a few more mollusks to the list.
Northern bay mussel.
Schizoplax brandtii
This is one of my personal favorite chitons.
Buccinum baerii
I must have misunderstood but do not wish to derail this lovely thread. Apologies.
(Introduced from where?)
I saw this and was thinking about how few arthropods are blue, I think pelagic animlas tends to be blue to blend in with the open sea, like the blue shark, blue fish, and blue whale
As well as the shortfin mako shark, and many other fish
As an arthropod specialist most of the blue things I observe are flowers
Most of my “blue” photos are of flowers, but that would be too easy. Finding blue arthropods is much more difficult, but here goes with a few:
Celastrina argiolus, hard to get more blue than this!
Orthetrum brunneum
Limenitis reducta
Anthaxia thalassophila thalassophila
Blue winged kookaburra https://inaturalist.ala.org.au/observations/90006257
Cape starling https://inaturalist.ala.org.au/observations/207132670
Burchell’s starling

Superb starling

Wow, that Orthetrum looks amazingly like a New World pondhawk (Erythemis), specifically Eastern or Western Pondhawks. Also very blue.
Wow, I love this photo!
Centaurea cyanus (Cornflower · 수레국화)
Commelina communis (Asiatic Dayflower · 닭의장풀)
Macrophthalmus japonicus (칠게)
Tubuca arcuata (Bowed Fiddler Crab · 농게)
Charybdis japonica (Asian Paddle Crab · 민꽃게)
I love those crabs.
Lots of beautiful blue underwater!
