Definitely true, the hive life cycles with the solstice and equinox. But the extent expressed is regional. Where I am, LoL, brooding is waaaaaaaayy off on my local weather radar. It will be at least 3 months here before they start anything substantive. For now they are in maintenance mode only, brooding smaller than one or two palm sized patches.
Looking out the window, I just realized that my deep freeze food storage chest is 24 degrees Celsius ( 44 deg F warmer ) warmer than it is outside right now. Yes, am saying that my freezer is much warmer than my bbq patio chairs.
