Isoneurothrips australis Bagnall lives in the flowers o, Eucalyptus trees. Knowing the mean number of thrips per flower, an estimate of the number of flowers was required so that the number of thrips in an isolated patch of scrub could be calculated. Flowers were sampled by two methods and the results compared and combined. The propriety of using probabilities higher than 0.05 for the calculation of confidence limits is discussed.
