“…This could account for a large portion of our differences. For instance, Osmia lignaria, which was common in Krombein's study, was never trap-nested in our study, though it is regularly trap-nested on structures in the Athens, GA vicinity (Matthews and Kislow, 1972;Mitchell, 1962). …”

“…Studies suggest that either the location of the provision inside the cell or, more probably, the partition walls are the possible directional cues used for cocoon orientation (Matthews and Kislow 1973, Johnson 1980, Torchio 1980). The location of the provision varies with species (Vicens et al 1993), but the shape and texture of partition walls are similar in most species, being rough and convex toward the entrance but smooth and concave towards the end.…”

“…In wasps, more than 99% of cocoons are oriented properly ( Cooper 1957 ); however, in the red mason bee, 3–10% of females and as many as 19–29% of males are misoriented in cocoons ( Szentgyörgyi and Woyciechowski 2013 ). Studies suggest that either the location of the provision inside the cell or, more probably, the partition walls are the possible directional cues used for cocoon orientation ( Matthews and Kislow 1973 , Johnson 1980 , Torchio 1980 ).

Numerous species of solitary bees and wasps build linear nests with only one entrance. Developing insects must orient themselves inside their nest to choose the correct direction in which to emerge. Misorientation and chewing towards the dead end of the nest can result in significant mortality. Most insects position themselves towards the nest entrance during cocoon construction; however, some individuals are misoriented. We tested whether imagines can examine and possibly correct their orientation after emerging from their cocoons. Males were usually able to correct their misoriented position based on the shape of the cell wall and emerged through the correct entrance, whereas most females pursued the direction that they faced in their cocoons. We suggest that there can be more than one time point during development when bees can control their position in relation to the nest entrance and that the importance of these time points varies between sexes.

International audienceProper orientation of cocoons in linearly structured nests can be crucial for the survival of hatching bees. Nevertheless, misoriented cocoons appear in nature in notable proportions. A detailed analysis of sex, space available for cocoon spinning, cocoon size, and nest diameter in the red mason bee (Osmia bicornis) showed that smaller males are more prone to misorientation than larger females. Generally, smaller individuals of both sexes are more often misoriented because smaller larvae disregard the direction of the entrance during cocoon construction. Moreover, cocoons in stems of smaller diameter are less often misoriented than bees in wider nests. Our results suggest that cocoon size and available space are the most important traits affecting cocoon orientation
