Chrysoesthia sexguttella, the orache leafminer moth, is a moth in the family Gelechiidae. It is found in all of Europe, east to southern Siberia, as well as the north-eastern parts of North America, where it might be an introduced species.
The wingspan is 8–10 mm. The head is metallic brassy-grey. Forewings are dark purplish-grey, mixed with black, with some whitish scales; a yellow subdorsal spot in the middle, and a smaller one in disc posteriorly; an ill-defined ochreous-white tornal spot, and another on costa at 3/4. Hindwings are grey. The larva is yellow-whitish; dorsal line brownish; lateral line of orange -reddish spots; head pale brown; plate of 2 blackish.
Adults are on the wing from May to June, and again from August to September. There are two generations per year. The larvae mine the leaves of Atriplex species (including Atriplex cakotheca, Atriplex hastata, Atriplex hortensis, Atriplex littoralis, Atriplex prostrata, Atriplex nitens, Atriplex patula and Atriplex sibirica), Chenopodium species (including Chenopodium album, Chenopodium bonus-henricus, Chenopodium giganteum, Chenopodium glaucum, Chenopodium hybridum, Chenopodium murale, Chenopodium opulifolium, Chenopodium polyspermum, Chenopodium quinoa, Chenopodium urbicum and Chenopodium vulvaria), Amaranthus blitum, Amaranthus caudatus, Bassia scoparia and Spinacia. They form a contorted gallery on the surface of the leaves. Wikipedia →

Rare
Under 5% of wildlife watchers report an Orache Leafminer Moth sighting in Boston on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 297th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report an Orache Leafminer Moth in Boston on a given day, against under 5% in October to May, the lowest months.
3rd of 14
Of the 14 cities where we can rate Orache Leafminer Moth sightings, Boston ranks 3rd at under 5%. The best odds are in Philadelphia (United States, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Orache Leafminer Moth is recorded against all the insects logged in Boston (44 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
