A pair of Sachems (male at left and female at right). Sachems are occasional visitors to Ohio. They do not overwinter here, but they periodically migrate from the south. Their numbers fluctuate from year to year. In some years, they are uncommon, but in other years, they are almost commonplace. As with most southern migrants, you are most likely to see Sachems in late summer and fall. I have never seen a Sachem before mid-July, but they can linger well into October (weather permitting).
Male Sachems tend to be more golden in color, with a large, irregular yellow patch on their hindwings.
Female Sachems have large white spots, visible when their wings are spread.
Sachems tend to be larger and more elongated than our other grass-skippers. Females, like the individual at left, are usually brownish with a chevron (V-shaped band) of white dots.
Another male Sachem, nectaring on blue mistflowers. The shape of the yellow patch is variable from one individual to the next.
Male Sachems have a distinctive large, black, rectangular stigma.
