The frequency of butterflies with O.elektroscirrha spores remained about the same between sites and throughout the winter. 2 The spores, recovered from all parts of the body of the butterfly, were most numerous on the abdomen, particularly near the posterior third. 3 Butterflies with spores survived as long… CONTINUE READING
