Cankerworm City -Edit-

with one comment


ok, I goofed. Its not a Paleacrita vernata.

It’s a Alsophila pometaria.

According to a real entomologist.

Arthur V. Evans

I stand corrected.

My Bad.

Thank you Dr. Evans.


These guys are everywhere!

Some one set off the inchworm bomb!

People in the “know” call these guys Cankerworms.

Some people call them Inchworms.

Some Latin people call them Paleacrita vernata. (there is no italics button on a smartphone)

The Latin word Vern means “the spring”

These are the larvae of the Geometer Moth or Geometridae family. (from Greekgeo γη or γαια ‘the earth’ and metron μέτρων ‘measure’ — refers to the larvae, which appear to “measure the earth” as they move in a looping fashion)

Generally you can find the moths from winter to late spring.

So these guys drop to the ground. Eating a few broadleaf trees and shrubs along the way. The larvae find a nice spot in the soil or debris and pupate without making a cacoon.

They spend the whole next winter as pupa. Then… The cycle continues.

  1. Nice informative lesson on the inch worm. Tis a pretty dull life for the little ole cankerworm, except for the part where they get to skydive from the trees by their little silk strands, freaking out all who walk below. . They dont even get to make a coccoon?! Bummer.
    Thanks, mr lee 🙂
