Caterpillar Head Anatomy by HedwigtheStrange Caterpillar Head Anatomy by HedwigtheStrange
A generic caterpillar head for to showing anatomy.

Sulcus: generally means a depression of some sort, here the sulci are also cleavage lines. This means that the cuticle (exoskeleton) will split along these lines when the caterpillar molts.

Frontoclypeus: a plate of exoskeleton above the labrum.

Stemmata: larval eyes similar to ommatidia (the units of adult insects' compound eyes), but simpler.

Labrum: Sort of an insect upper lip.

Vertex: Forehead, more or less.

Gena: Area around and below the stemmata. The equivalent of cheeks on a human.

Setae: Hairs. Caterpillars gain more hairs every time they molt.

Mandible: Chompy bits.

WHHOOOWWW! What an illustration!
A work of genius Hedwig! Let me know if ever you produce a book of Arthropod anatomy!

This is brilliant and exactly what I had been searching for. I was showing my mom microscope photos of some cats and we were trying to figure out what all the parts were. Thank you so much for sharing this! (And also, if you have any shortage of black swallowtails to study, I've got a plethora of photos and video I would be happy to share).

Magnificent work. Very clear, and very attractively rendered.

I'm surprised it merited a "magnifcent"! Thanks!

Surprised? SURPRISED? Didn't you LOOK at it??? Or did you just draw it without noticing it?
Please note that it is not just aesthetically pleasing, it is striking, informative and accurate. Show me a few textbooks with illustrations to rival this, then come back and tell me how  surprised you are! I want a copy of the first edition of your first book on insect morphology!

Ah takes me back to when I had a pet caterpillar, who I would stare at for days while he ate. His name was Happy... ; ;
Great illustration too, everything is quite clear - so they don't see out of the top yet? They look kinda like compound eyes.

No, they don't have compound eyes yet, but the shape of the head gives the suggestion of large eyes. Maybe to make them look overall larger and scare off predators?

I'm sort of frustrated with how this looks... I like the caterpillar head itself, but when combined with labeling and background color, it's kinda boring. Any thoughts on how to improve that?
Banvivirie Featured By Owner Mar 8, 2011  Professional Traditional Artist
maybe change the background color to that dark brown of the stemmata? The labels might pop a little more if you change their color to the brightest highlight, or every other label white and olive green. As for the composition itself, I think what is most bothersome is the two left-aligned lists, on the sides, with a lot of confusing lines going every which way. If it's possible, you could try arranging the labels in a circle, or color-coding.
I don't think it looks bad the way it is now, but those are just some things you could mess with :meow:
