laquthenus asked:

What kind of caterpillars there is!? That sounds horrifying thing! I'm so glad that here in Finland isn't such horrible caterpillars (at least what I know). And I'm so happy that your dog is now ok!

Thaumetopoea pityocampa

And it’s called “procesionaria” because the caterpillars form a row, you know, like in a procession. Not only is bad for animals or humans but also for the trees. I’m not going to posts pics of the wounds these caterpillars do because it’s horrifying. If you are feeling like it, you can look for photos…

And thank you. Btw, the little shit is called Rina and she’s stupid…. she’s lucky we love her.


photos by samuel jaffe showcasing the diversity of massachusetts’ caterpillars. notes samuel, “my goal is to share all the secrets i have gathered about our local environments and about the value of our backyard ecosystems. i hope to show people that we do not need to look to far away places to find the beauty of nature. nature is all around us, under our feet, and in our daily lives.”

If any of you are ophidiophobic the Department of Awesome Camouflage would like to offer reassurance that, no matter what your eyes or adrenal cortex are trying to tell you, the animals in these photo are NOT snakes. They’re a wily species of caterpillar that wards off predators by expanding and turning the end of its body, which bears the unmistakable markings of a snake’s head on the underside. If approached, they’ll even go so far as to strike like a real snake. These strikes are completely harmless, but they look so convincing that we’re pretty sure we’d flinch all the same.

This fascinating photo was taken by Daniel Janzen, a biology professor at the University of Pennsylvania, in the Area de Conservacion Guanacaste in northwestern Costa Rica. He’s working there cataloguing caterpillars and says this specimen is a member of the genus Hemeroplanes

This Remarkable Bird Pretends to Be a Bug

A study recently published in the journal American Naturalist details how the cinereous mourner (Laniocera hypopyrra) is covered with bright orange and speckled down-feathers when it is first born. Not only does this soft plumage make the newborn birds looks like one of two large and hairy toxic caterpillars (Megalopyge or Podalia), but the birds will even wriggle like massive bugs for the first 18 days of their life.
