The number of suni bug imagoes was determined during autumn at overwintering sites over a period of 30 years (1964-1993). At Fruska Gora and Deliblatska Pescara locality in Vojvodina, Serbia (Yugoslavia), 5844 samples were inspected and 42700 imagoes of suni bug were collected. The number of insects varied. It ranged from 7.2 to 220.1 imagoes per square m. High population density of suni bugs was registered in 1964, 1968, 1969, 1970 and 1993. In 1973 and 1988, the number of imagoes was close to the level of tolerance. In all the other years of the trial period their number was less than 20 imagoes per square m. Considering the representatives of the population in Vojvodina, the most numerous was Eurygaster austriaca, followed by E. maura. Average sexual index at both localities was 1 : 0.9 (female : male) for E. austrica. and 1 : 0.8 for E. maura.
