| Weekly censuses continued until 10 September 2000, when new wasps were no longer eclosing and gynes were cannibalizing larvae. |
| The report draws on the 1996 and 2001 censuses, which contain a 10 percent and 16 percent undercount, respectively. |
| For males, we noted all territorial and courtship behavior during censuses and used this information to determine the social status of a male. |
| Direction and density of nocturnal migrants detected with radar and ceilometers were compared with changes in species counts from daily censuses. |
| All mortalities are given per million population, with population sizes derived from censuses by interpolation or extrapolation. |
| Profitability depended on accurate data and life assurance companies were active supporters of population censuses initiated by the government. |
