Specimen type: Photograph
Observation notes: Sighted moving half of the Spirea bush by wiggling like a "Slinky™" up a branch to eat leaves & autumn weathered post bloomed flower tops, I see they tend to love. This is the largest and darkest one that I've seen so far this year. Accurate account and complete size is approximately 2¼" inches/62mm-long when stretched//, 1¾" when rentracted//½" inch/12mm in body diameter and ⅝" inch/15mm total circumferance with the wool/hair taken in account. There are 8 Yellow spots visible at just forward on the side of each cell segment, as well as one on mid center of nose. The "eye" pattern, being a white "ll" with a black "pupil" is clear and visible, as is all 6 mandible "legs", 5 pair of thoracic legs with suction feet, and a pair of anal thoracic legs. Very bright & shiny being it that it is dry.
