occlusor muscle of adult abdominal spiracle [FBbt_00059065]

A short muscle that functions in closing an adult abdominal spiracle. These muscles are attached to sclerotised lever which is in turn attached to a deep fold in the wall of spiracle at the base of the spiracular chamber. The other end is attached to a rigid part of the wall of the spiracular chamber so that its contraction closes the passage. There is no dilator muscle so the passage is probably kept open by its natural elasticity (Miller, 1950 pg 459).
