Black Firefly image?

I've been grinding out the last few achievements, and the only ones I have left are the time based ones, kitten training, "World Domination", and catching a black firefly.

I was lucky enough to find all of the other rare prey either by short grinding sessions, or just by normal hunting methods. The thing I noticed is that all other rare prey have a fairly unique appearance from others of their kind (blue jays and cardinals have striking colors, the Lunar Butterfly glows, etc.). Since fireflies barely stand out from one another until they flash, I was wondering if the black ones had a similarly striking feature that made them easy to spot. I don't have the best eyesight for picking out subtle differences quickly, so knowing exactly what to look for helps a TON.

So, are there any pictures of LIVE black fireflies in game? Or videos? everything I've found so far is what they look like when you put them in your home, which is only mildly helpful if I kill fireflies randomly.

Thanks in advance!

UPDATE: OK, so only after another 10 minutes of grinding, I finally found one! While they are relatively easy to spot, they do only "glow" about as often as the other firefly variants. That being said, they are black in color compared to the whitish-grey color of the normal ones, so you should be able to spot them while they aren't glowing.

If anyone still have an image or video that can show this that'd be great! I don't really have a setup to record, and I was too excited when I saw it to try and screen cap it...
