Figures 5-8. Scanning electron micrographs of paper from nests of M. m. 
cubicola. 5, Cap on cell of a late pupa (nest #9, June collection, 31 cells), showing 
wood and other debris deposited by adult wasps, thus giving the cap a cryptic 
appearance (50X). 6, Paper on outside of same nest, showing its non-woody, well- 
worked surface (500X). 7, Pedicel of same nest, showing extremely smooth texture 
(100X). 8, Pedicel of smaller, newer nest (nest#l, June collection, 44 cells), showing 
loose nature of woody constituents (100X). 
Defensive Behavior other than Architectural 
Young Colonies 
Attack behavior as studied by numerous individuals and reviewed 
by Hermann and Blum (1981) appeared to be non-existent in this 
species during early colony life. However, a pseudoattack was 
elicited from wasps upon strong provocation. Strong provocation 
was carried out by tapping on the leaf upon which the nest was built 
or by actually touching the nest. Pseudoattack is defined as adult 
flight from the nest in the direction of the intruder. This differs from 
escape in which flight is not directed toward the intruder. 
Pseudoattack is readily demonstrated in other local polistines, e.g.,
