Table 2 gives % Items for 2007, and Table 3 gives % Items for 2008. In both tables, relevant data are split between the two "Arthropod in crop (proportion)" columns, one for adults and one for larvae.
No need to enter 0's or "-"s. Note that inexplicably, Table 2 only sums to 91%. Make a note of this in the Notes field.
