(a) Flowering calendar
(b) Estimated date for making a pollen ball
Figure 2: (a) Flowering phenology on the Isikakri Coast and (b) oviposition dates (i.e., dates when pollen balls were made) inferred from the rearing of immature individuals in the laboratory. Nests with pollen balls, eggs, larvae, pupae, and adults were sampled on 1 July. The thick line in (a) represents the starting dates of the flowering period of each flowering species at the field. The date axis in (a) is common with in (b).
