Oligoleges! If you know the meaning of “oligoleges” before I tell you, then you know too much stuff!!
In my extensive research of plants for this blog (web surfing), I learn so much. It turns out that some species of bees will only collect pollen from certain plants. They are so specialized to a species or genus of plant that no other will do. This is called oligolecty and the bee species that do this are called oligoleges. The oligoleges of Partridge Pea are Anthophora walshii and Svastra atripes atripes. Now you know something new!
It turns out that researchers are not completely certain why some bees are so specialized , although it probably has something to do with amino acid composition in the pollen.
