The ninth 節気 “sekki” division of the traditional Japanese calendar is:
芒種
(ぼうしゅ)
“bōshu”
‘grain beards and seeds’ // ‘grain in ear’ (solar term)
The first “kō” microseason within this division is:
蟷螂生
(かまきり しょうず)
“kamakiri shōzu”
Praying mantises hatch
That makes 蟷螂生 the twenty-fifth microseason of the year!
It typically lasts 6~10 June.
