Seasonal Abundance

Information as to the relative seasonal abundance of L. excelsa may be obtained from data attached to the specimens that have been preserved in the various collections examined, and from personal collecting. The following Table gives the percentage monthly occurrence of adults throughout the year. The total number of records used in computing the following figures was 82, covering a period of random collecting over a period of thirty years, together with some personal records from the Nelson District over the past two years; these figures are shown graphically in Fig. 4.

The main flight periods of adults of L. excelsa would appear to be March and April, and June, and to a much lesser extent in May, November and December. The sexes show no differences in seasonal occurrence.
