Bag worm

Oiketicus kirbyi

Description:

It is eating guava leafs in the pictures ( guayaba ) I'm sure it can see at all because it doesn't react to me or my movement, but if I cause almost an imperceptible vibration it gets into its bag.

Habitat:

My backyard!

It is quite a pest for several crops in the neotropics. The female has no antennae and no wings, does not leave the bag (!), is neotenic (also known from the Axolotl), meaning the fertilization occurs in the larval-like (but adult) stage of the female (!) by the male which opens the female's bag for mating. The female at the end is very large due to the mass of eggs (some thousands!). At the end the female drops to the ground and dies, the bag and the eggs remains attached on a leaf or little branch. Just some short info about an exciting, strange and complex behaviour!

Maybe it was a male caterpillar, because if it didn't want to eat more was because it was ready to change to a butterfly

Also I wanted to tell you that my mother's garden is a weed garden she does not have a guayaba tree and there is no guayaba trees around, this bagworm will try to climb up high at any cost, I followed it for three days doing that until it found the wall and climb 2 stories high and there it stayed.

I also found one of this Bagworm's in my mother home in San jose, I have it under an ID, I worked out by investigating and researching for some time.
I will also check your ID and if needed I will edit

It is most of the time not clear if this is the caterpillar or the adult flightless female.

That's cool that you have your own monster in your backyard.

It's a little hard to see the back of the animal, due to extreme closeup (WOW, btw). However, at this angle I definitely award this creature the "uglist insect award". Just, wow.
