Development — Two methods of spread of the disease. 1st, spores 

 scattered on leaves are swallowed by young caterpillars, the polar 

 filament is expulsed, the capsule splits and an amoeboid trophozoite 

 emerges which bores into the tissues of the caterpillar. 2d, the 

 parasites reach the ovaries and infest the eggs of the host. From 

 these infested eggs are hatched weak, diseased caterpillars which, 

 though they soon die, contaminate the food.
