S ummary . The replies to a questionnaire sent out to a large class of sheep owners and pastoralists in Tasmania indicate: (1) that Oncopera intricata (Walker) is a pest of first‐class economic importance in the State of Tasmania, precluding as it does successful pasture production over large areas of the country; (2) that grasses with a mechanism for natural vegetative propagation, e.g. stolons, etc., are likely to persist through a severe attack and by their recovery after the pupation of the grass‐attacking larvae provide some return rather than allow the ground to go out of production or be covered by unprofitable weeds; (3) the replies plus external evidence show that a sward of creeping grasses and clovers will be likely to be most useful.
