The average inside diameter is greatest for C. planatus (4.73), 
surprisingly large for S. picta, which is such a minute ant, and 
smallest for P. pallida (2.38, single chamber). The average diameter 
of internodes occupied by P. pallida and T. littorale does not differ 
significantly (t-test, t s = .70, p > 0.5). 
As shown in Table 2 the internode occupied by the nest parallels 
the results of internode diameter. Since larger internodes are lower
