Typical insect stretch receptors and receptor-like organs present in larvae of Sarcophaga bullata and other flies contain associated cells which are suspected of passing secretory products into "target" organs by way of strands of connective tissue. In the fly larva, such organs are attached to leg rudiments, tracheal discs, muscles, the genital disc and gonads, and may be concerned with the neuroendocrine control of metamorphosis of these structures.
