It depends on the season. Sometimes a colony can be starving late in the summer. Sometimes the bees can already have kicked out the drones because the income is sparse and stores are low.
Bees do not starve by calendar dates - it depends on the season. If the winter season (between autumn and spring) is short and they start off with lots of stores (and bees die off in the winter months, for whatever reason - often due to varroa nymphs feeding during pupation or beekeeper interference) they may not have sufficient space to brood in spring (and too few bees to build up quickly).
Alternatively they may be starving by the time they should be building up for the new season ahead. In nature, the colony would peg, but the beekeeper can feed extra stores as necessary - but only by knowing the conditions in the hive - that means knowing how well they were provided with winter stores, that winter bees would not be dying off due to varroa infestations and how much stores might be left after the winter (hefting is one way of checking).
Some years it has been known that bees have needed feeding until as late as May, or they may have died due to starvation. If you keep bees by the calendar, you could have lost a lot of colonies before the summer season had even arrived! That particular year, I supered my bees late March (OSR was already well in bloom and the weather was good), went on holiday to Spain for about ten days - and then removed the supers on my return as it was wet and cold (and remained wet and cold the whole of April and into May). I didn’t lose any colonies, did not actually need to feed (it was a fairly marginal decision at times), but neither did I get the expected decent OSR crop that year.
