We’re in Osaka, Japan, living in a 10th floor apartment, so whatever laid that egg was a good flier. It’s about 7 cm long, and chowing down on raspberry bushes. Any idea what it will become? The picture was taken about a week ago (May 24th).
Thanks!

Inchworm

Inchworm

Hi Chris,
This appears to be an Inchworm or Spanworm in the Moth family Geometridae.  Most caterpillars in this family have only two pairs of prolegs which causes them to move in a most characteristic manner, where the caterpillar stretches out with is true legs and then moves the entire hind section in one step, inching along and causing the body to loop.  We are not certain of the species.  Most Geometrid Moths are dull in color, but some are quite colorful.

Dear Adriana,
This is an Inchworm or Spanworm in the family Geometridae, and the common name for the caterpillar is because of the number of prolegs, two pairs, resulting in a manner of locomotion where the caterpillar stretches out with is true legs and then moves the entire hind section in one step, inching along and causing the body to loop in the manner illustrated in one of your images.  Interestingly, our first attempt at a species identification, thank to your inclusion of the food plant Penstemon in your description, produced a matching image from our archive that has been unidentified to the species level since April 2008.  We hope to remedy that identification plus your identification today.  Without too much trouble, we located
 Meris paradoxa on BugGuide.  The host plant is listed as snapdragon, and Penstemon is in the snapdragon family Plantaginaceae.

Thank you so much for solving the mystery.  I looked all over the internet for a couple of days before I asked for your assistance.  Wow, such a colorful caterpillar turns into such a drab moth.

Dear CC,
We are splitting your identification request into two distinct postings to better conform to our categorization.  Your first caterpillar, the Inchworm, is a Woolly Gray Spanworm,
Lycia ypsilon, which we quickly identified on BugGuide where it is noted:  “One of only a handful of brightly colored inchworms in the East.”  This is a new species for our archives.

I’ve just found this clinging onto a photo in my room, looks like a twig but has four stubby legs at the front… Never seen anything like it! Hope you can help! Got to admit I don’t really want him in my room but don’t have the heart to put him outside in winter…
Thankyou! Emily :)

Hi Emily,
This is the caterpillar of a moth in the family Geometridae.  They often mimic twigs and they are called Inchworms or Spanworms because of the manner in which they move, bunching up the body and then stretching out again.

I found this strange thing crawling on the exterior of my house. I live just west of San Antonio Texas and the time of year was the fall. I was using a z tool to try and grab it off the wall and as soon as I got near, it acted as if it sensed something and kind of stood up on one end as if it was afraid.
