Choice of flower colour by hawkmoths during day and dusk light conditions and by naïve and experienced bumble-bees on flowers with similar or different pollen rewards

Pollinator	Experiment	n	Preference	Test/Procedure	P-value
Hawkmoth	Day	32	Blue	Binomial	0·025
	Dusk	6	Blue	Proc Mixed	0·030
Naïve bees	Similar reward	185	Blue	Z = –3·13, Proc Glimmix	0·002
	Different reward	>120	Rewarding flower	Z-value (see text), Proc Glimmix	<0·0001
Experienced bees	Similar reward	157	None	Z = –1·39, Proc Glimmix	0·166

The Proc Mixed and Proc Glimmix are SAS procedures for Linear mixed models.

The variable n for the binomial test represents the number of trials, for the Proc Mixed the number of days, and for experimental arrays the number of flowers.
