The results show a decline in the number of species of Scarabaeinae and a shift in species compo- sition. Possible explanations for the changes include vegetational-climatic differences over time and the recent increase in the number of the red imported fire ant. },

Neither of these was recorded during a similar survey 10 years previously. Three uncommon species recorded in the earlier survey were not taken in 1985. The appearance at Welder of O. gazella since 1975 illustrates a successful introduction, whereas the appearance of O. alluvius seems to be the effect of a well-documented increase in annual rainfall.},
