Crimea ; U. The first instar remains free, the second becomes attached to a thoracic tracheal trunk of the host near the spiracle Phorocerosm forte is reported by Iwata and Nagatomi to attach itself to the tympanumby its single pair of functional spiracles, which are situated a t the posterior end, and are large and protruding, projecting into the trachea of the host; the host reacts by producing a conical brownish sclerotised respiratory funnel enclosing the posterior segments of the parasitic larva, which lies in the fat body with its head towards the posterior end of the host.
The fully-fed larvae remain quiescent until the following spring in temperate climates, or until rconomia next rains in tropical countries, when some pupate. Results of a mission of the Iraq Department of Agriculture to Balcuf.
