In four days, I am heading to Vancouver, BC (Canada) to do some biology-based exploring, much like Ed Ricketts did.

I won't have access to a car, so I'm at the whim of public transit and my friend's wishes in order to get to any beaches. I'll be sure to post photos of any critters I find.

I will outscream the cicadas

justfuckhimalreadydean

Can I ask what are cicadas

vanishingactblog

Demonic, red-eyed hoards of insects that rise from the ground en masse to shed their skins all over tree trunks and SCREAM NON-STOP ALL DAY UNTIL IT BECOMES A KIND OF WHITE NOISE THAT YOU DON’T EVEN REALLY HEAR ANY MORE.

Reblogging just for that description

These are cicadas

i have no idea if these cicadas are alive or dead or shelled, but it doesn’t matter, because they’re all equally chill and will sit on you if you don’t eat them

they come out once every seventeen years to swarm, buzz, mate, and die. while they’re doing that you can coat yourself in chill cicadas and be the cicada king. they don’t bite or crawl. just chill.

Well. They don’t just chill.

They also scream

Well yes the PERIODICAL cicadas (genus Magicicada) come out all at once every 17 (or 13) years, and this description is pretty accurate (I love the girls with all the molts!!). However, there are plenty of annual cicadas (multiple genera) that breed every year, and they also scream - if you live in the eastern half of North America there’s a good chance you’ve heard them, you just didn’t know it! The cicada in that last photo is a freshly-molted annual species, not a periodical cicada which, as stated above, do indeed have red eyes:

Insect eggs: extraordinary examples of organic architecture

The eggs of different insects vary greatly in size, shape, and color. Engineered for survival, insect eggs show stunning surface structures. Insects produce a lot of eggs, each of them surrounded by a shell (the chorion) which can be ornately sculptured with ridges or spines. Some insect eggs are covered by additional protective cases, sacs, or foams.

I’ll be posting some amazing examples of insect eggs. This first photo shows an egg of the Adonis Blue, an European butterfly of the species Polyommatus bellargus [Syn. Lysandra bellargus], in which it can be seen the so called aeropyle system of the egg following a mathematical rule called the Fibonacci Series.

The aeropyle system is the heavily ornamented networks of interconnected pores of the shell (chorion), developed to guarantee sufficient oxygen diffusion during the development of the embryo caterpillar.

The Adonis blue butterfly is rare because it’s choosy. It lays its eggs (like the one above) only on horseshoe vetch, a European perennial. What’s more, it looks for patches cropped by rabbits that allow easy landing.
