From padellus taken from cherry seedlings in New York we have bred a few specimens of Mesochoriis sp., while the most common parasite of both padellus and malinellus was the tachinid, Exorista arvicola Meig. Some colonies had as many as 25 per ct. of the caterpillars carrying from one to three eggs of this fly, which were in the constrictions principally of the head and thoracic segments. The eggs are of a cream color and measure about .52 mm. long,.
