Pine Processional Caterpillars
Pine Processionary Moth (PPM) larvae (caterpillars) feed on the needles of pine trees and other conifer tree species, forming candy floss-like cocoons. In large numbers they can severely defoliate trees, weakening them (above photos) and making them more susceptible to attack by other pests or diseases, or to environmental stress caused by drought or rainstorms. PPM gets its name from its distinctive habit of moving about in nose-to-tail processions:
They represent a public health hazard because they have thousands of hairs which contain an irritating protein called thaumetopoein. These hairs can be blown by the wind into contact with people and animals, resulting in painful skin irritations and rashes and, sometimes, allergic reactions in people and death in animals.
This is how a healthy Mediterranean Umbrella pine should look:

Yikes! We've had a problem here with pine beetles killing off pine trees. As a certified tree hugger, I have issues with that!
What a beautiful little tree killer!
I have pine trees, but I've never seen those and hope I never do!
I have never seen such a parade. They'd be really cool if only they weren't so destructive.
Isn't nature strange, something so clever to watch causing so much devastation
Great post for P and love the catepillar photos ~ thanks, ^_^
Wow - amazing caterpillars!
What a shame these caterpillars are causing such problems!
Yikes -- evil looking little beasts! Growing up, there were similar looking black caterpillars everywhere -- beware if you stepped on one on the sidewalk!
tienes un perro precioso, jo tambien tengo un westhi, aunque son un poco cabezones pero son una maravilla, felcidades por tu bloc me encanta.

Caterpillars have always scared me. I am not a fan of small things that can crawl.
What horrible pests!
A great post, interesting to study all details!
In Georgia, we call these "tent caterpillars," and my father used to make a torch of old rags and gasoline, light it, and burn the tents before they could spread.
wow, a marching, munching army!
Seriously busy caterpillars, wow!! Thanks for sharing the love up-close with I Heart Macro:-)
Who knew a caterpillar could be so hazardous... cool!
OH my gosh -- there are one trillion of those guys on that tree. Yikes! Very interesting information but scary!
Wow, they are dangerous caterpillars.. They are amazing to see! Great series! Have a happy weekend!
Whoa, great captures and thanks for the warning!
In France, we call this specie : "processionnaire du pin"... That is a curiosity of nature, nice report.
Well...those certainly are destructive little buggers!! Hope all is well with you two! xo Jeanne, Chloe and LadyBug
even before reading about these pests, I knew they were not good visitors to the tree. thankfully, I did not lose a tree once inhabited by these "robbers"!
The spiny caterpillars are a pest - around the northeast USA, it is the gypsy moth caterpillars that denude leafy trees, so these can be terrible pests. It si a shame to see the conifers minus their needles, and a tree that is without green is a sad looking tree indeed. How to get rid of these pests is a mystery...that we hope to find a way to do so...
Well at least the caterpillars are kind of cute! Have a lovely Sunday.
Oh no, right now I'm happy living in Finland where we don't have this kind of killer!
ps. Thanks, I feel much better than a week ago!

I had never heard of these guys ... Great photos and great post ... Thanks so much for sharing this at Our Beautiful World
Wow! Truly amazing. I've only ever seen one of those caterpillars at a time. But an army like that? Woah! Thanks for sharing.
We get tent caterpillars and they can devastate a tree. Fortunately they only have a huge impact every ten years or so when there is a population explosion. That gives the trees a few years to bounce back in between. -- Margy
Beautiful little critters, but it`s bad to see how the destruction they make. Great pictures, and thanks for the lesson :)
Whoah! I've seen these in Philippines and they freak me out! Nice post!
Hugs,
Melody and Olivia xx
Yikes!! That's scary!
Scary stuff! Why are so many things in nature so destructive? Drat! Thanks for sharing.
