Not only that, but monoculture is bee bonanza one time of the year and a wasteland in the rest. Unsurprisingly, bees need to eat the whole year, and they prefer a variety of plants and flowers which mature at different times. A diversified garden or farm supplies them thorough the year.

Bees are not the worst case because they can make honey to prepare for lean times. Insects which don't stockpile long-term reserves are out of luck.
