Aphid bet /// Failed.
Based on the Weather Bureau's predictions, tomorrow (Friday) should be the last warmish day of the year. Therefore tomorrow should be the Big Day For Aphids. I've seen only a few of them today and yesterday, so they'd better get their cloned butts in gear.
Next day: Nope, no aphids at all. Bureau was wrong.
Here's the pattern as of last year at this time:
This is the seventh time I've noted it here. Aphid Day in 2010 was the first of Oct; in 2011 it was the end of Oct; in 2012 the first of Oct; in 2013 the last part of Oct; in 2014 the end of Sept; in 2015 end of Sept again; now in 2016 end of Sept.Most of the pattern was alternating end of Sept / end of Oct. The majority pattern would favor end of Oct this year, so absent aphids right now shouldn't be a surprise. 2015 was either a mode change or an exception. If we do get the aphids at end of Oct this year, 2015 will look more like a single exception. They arrived Oct 19 which isn't exactly 'end of Oct' but close enough for Nature work.
