anterior spiracle primordium [FBbt_00017001]

Primordium of the anterior spiracle of the larva. Originates in the posterior third of the lateral ectoderm of the prothoracic segment during stage 14. A group of cells that are more basophilic than those surrounding them fuse with the tracheal pit of the mesothoracic segment (tracheal metamere 1).
