This kō opens 芒種, whose own name is a direct agricultural instruction: 芒 refers to the bristly awn on a grain husk — barley, wheat, rice — and 種 to sowing or seed, together marking the traditional window to sow awned grain and transplant rice seedlings into the paddy proper, the physically busiest fortnight of the farming year.
A mantis egg case bursts open now, and well over 200 nymphs spill out at once, already molted once and carrying the same folded pincers as an adult in miniature. Only two or three of those 200 will survive to adulthood — the overwhelming majority become food for something else before they ever get the chance to become predators themselves.
The praying mantis earned its place in a farming calendar honestly: it's a genuine 益虫 (beneficial insect), eating aphids and caterpillars off crops with an efficiency few other insects match once fully grown — a species that spends its entire early life as prey before becoming one of the more effective predators in the field.
Mild and delicate enough that it's traditionally cooked with its scales left on, fried crisp rather than removed.
Tart and firm compared to its cousin ume — eaten fresh rather than pickled, at its best while still slightly underripe.
The earliest corn of the year, sweetest within hours of picking as its sugars begin converting to starch almost immediately afterward.
Just coming into season — best sliced thin and eaten raw or barely blanched while the pods are still small and tender.
Kuchinashi's heavy, sweet scent carries much further than its modest white blossom would suggest — one of the few flowers in this calendar as strongly defined by smell as by appearance, often noticed on an evening walk before it's actually seen.
The seedlings raised in the nawashiro back in #17 are ready now to move into the flooded paddy proper — historically one of the most labor-intensive weeks of the entire agricultural year, done by hand in rows by whole communities before mechanization, and still marked by planting festivals (御田植祭) at certain shrines that reenact the process ceremonially rather than practically.
"The praying bug" — An old affectionate nickname for the mantis, describing the way its raised front legs fold together in a posture that looks, to human eyes, exactly like a person's hands pressed together in prayer — a resemblance the insect's own English common name landed on independently.
芒種, this sekki's own name, is unusually literal for the calendar: 芒 (nogi) is the specific word for the thin bristle on a grain husk, and the whole term simply instructs farmers on timing — sow the awned grains now. Few of the 24 sekki names are this directly functional; most describe what's happening in nature rather than what a person should be doing about it.
The papery, foam-like case (卵鞘) is easy to spot once you know the shape — finding one intact, just before the nymphs emerge, is rarer than finding one after.
A single adult mantis can meaningfully reduce aphid and caterpillar pressure on nearby plants over the following months.
Whatever the crop, the same logic behind taue applies broadly — established roots have a full summer ahead to settle in.
Cook it the same day if possible; corn held even overnight is noticeably less sweet than corn cooked within hours of harvest.
Out of more than 200 mantises hatching from a single egg case, only two or three will live long enough to become the efficient predator this kō credits the whole species for — the rest simply become food before they get the chance. The mantis doesn't know its own odds; it just does what a mantis does at each stage, prey until it very suddenly isn't. What are you doing right now that feels small or vulnerable, with no guarantee it survives to become anything more — and would you keep doing it anyway, odds aside?
