Periodical cicada nymphs from Brood XIII are crawling out of the earth and moulting on trees, leaving husks like in the picture. For the next several weeks they'll be everywhere in the affected area. Then they lay their eggs in young tree trunks and other such supple plant stems, which hatch later in the summer only to burrow back into the earth for 17 more years.
I may return with other cicada facts as more come out. Very curious to see if it's any different from the last time in 2007 due to climate change
It's funny I don't remember how we dealt with it at school. I just remember one of my friends collecting them in buckets. Plus my brother ate a wing on a dare and all the kids swore his hair grew half an inch overnight
