Morphology
geometrid = geometer (opaque) = geometr + id
The suffix '-id' marks membership (as in biological family terms), but knowing 'geometer' or 'geometry' does not allow a learner to predict that the word names a moth; the semantic shift is specialized.
Etymology
The word geometrid comes from Greek roots geo- 'earth' and -metron 'measure', the same root you find in geometry. It got this name because the caterpillars move in a looping, inching way that looks like they are 'measuring' the ground, so the name fits the moth and its inchworm larvae.
