In Class AB, Tables XLIV and XLV show that green flowers get the 
best visitors, and white flowers get, on the whole, better visitors than yellow 
flowers. In Table XLII it is seen that in spring many high types of insects 
go to AB. This is due to the frequent visits of Apis and Bombus to Acer 
P seudo-platanns and Salices — green flowers. If we take away Salix from 
Class AB, then we obtain Table XLVI :

And if we also take away Acer Pseudo-platanus we leave hardly any insects 
of high type for spring. 
The visitors to Salix which are, all but four, spring insects are : —
