Geometridae

New Artwork: Earth Measurer

An in-progress photo showing my contour drawing which underpins the finished painting!

I made the acquaintance of this inchworm at Whiterock Conservancy, and began the contour drawing over a year ago. I picked it back up this winter break!

The title of the piece, Earth Measurer, is the English translation of the Ancient-Greek-derived “geometer.” Geometridae is the scientific name for the family of caterpillars (and moths) that make use of the distinctive method of locomotion that is not only described in the family’s scientific name but also in many of their common names: inchworm, spanworm, looper, and measuring worm.

After spending a lot of time really looking at inchworm anatomy and learning terminology (FYI, they have true legs and prolegs), I am again impressed with the variety and richness of animal forms in the world; there’s plenty of alien to explore right here. This past summer, while painting mosquitoes from LSU Vet Med’s epidemiology department, I was surprised by how hairy they are upon examination. Similarly, on this so-called hairless caterpillar, there’s still a fair amount of hair, called setae! I included it in the painting as well, though you’ve got to get close to the painting or zoom in quite a bit to see it.

This is Earth Measurer, acrylic on basswood panel, 6x12x1.5”, 2023.
