An "unusual" find...

I only saw this when processing this picture. I went back to see if this "something" was still there and it was gone.
Any guesses?

[Mags]

How very different and weird!

[Corinne C]

So strange. I cannot tell!

[Tom]

For not seeing pretty darn cool

[Dorothy]

Certainly hanging on!

[Jessica Eby]

Cool shot! Some kind of inchworm would be my best guess!

[Casablanca 🇬🇧]

Google thinks it is a leaf beetle larva! But Google is not always right. Intriguing.

[KV]

Strange

[Beverley]

I think Jessica is right… a brave worm…

[Margaret Brown]

A strange one!

[Kate]

It does look like a worm

[Annie-Sue]

leech?

[Shutterbug]

I’d ask @karmahof. She is an insect expert. Looks like a terrific capture of it.

I 'believe' it may be a Blackberry Looper caterpillar
