The uncovered, single-comb nests of Mischocyttarus baconi Starr have short, stout, centric petioles. We describe nest size, cell size, petiole dimensions, and the position of the petiole. In a sample of 91 nests, the comb comprised up to 198 cells. Cells had a mean side-to-side diameter at the mouth of 3.4 mm. The petiole had a mean length of 2.9 and a modal width of 2.0 mm. The degree of excentricity was determined for a sample of nests of at least 20 cells. As expected, those attached to vertical substrates (wall nests) showed greater excentricity than those attached to horizontal substrates (ceiling nests).

1. Yearly records of worker Vespula germanica (Fabricius) taken in suction traps at Silwood Park (28 years) and at Rothamsted Research (39 years) are examined. 2. Using the autocorrelation function (ACF), a significant negative 1-year lag followed by a lesser non-significant positive 2-year lag was found in all, or parts of, each data set, indicating an underlying population dynamic of a 2-year cycle with a damped waveform. 3. The minimum number of years before the 2-year cycle with damped waveform was shown varied between 17 and 26, or was not found in some data sets. 4. Ecological factors delaying or preventing the occurrence of the 2-year cycle are considered.
