It is striking that the estimated total of about 1275 constructed<br />

cells greatly exceeds the predicted total of about 800 produced<br />

imagines - also when the fact was considered that cells in the<br />

upper comb had been re-used two or three times. This is explained<br />

by the great number of young in the cells of the outer zones of<br />

the intermediate and lower comb; cfr. the table, fig. 2g and fig. 3i,<br />

as this brood would not fulfil its development.<br />

The favourable weather conditions in the Bergen area from<br />

the end of April to near the end of June evidently gave the colony<br />

a good start. A growing number of energetic workers was responsible<br />

for a rapid construction of cells in the intermediate and<br />

lower comb and it may be too rapid for the inhabitants to take<br />

care of the young. However, more nests need to be studied to gain<br />

information about the specific biology of this wasp. More knowledge<br />

about social wasps in general, is also wanted for a discussion<br />

of the dissolution of nests under varying conditions.<br />
