This Caterpillar has long sticks attached parallel to the case axis to the top half of it's case, and short sticks to the bottom half at right angles to the case axis. Presumably the early instars of the caterpillar attach short sticks at right-angles to the case, and the later instars attach longer sticks parallel to the case as they continue to lenthen it to accommodate their growing bodies. The case can grow to a length of up to 4 cms.
