Eustroma reticulatum, the netted carpet, is a moth of the family Geometridae. The species was first described in 1775, by the Austrian lepidopterists Michael Denis and Ignaz Schiffermüller.
Description
The wingspan is {{convert|20|–|25|mm}}. There is one generation per year and the moths are on wing in July and August, flying from dusk. They come to light and can be disturbed by day amongst the foodplant, or can be seen resting nearby.{{cite book |last1=Waring |first1=Paul |last2=Townsend |first2=Martin |last3=Lewington |first3=Richard |author3-link=Richard Lewington (artist) |title=Field Guide to the Moths of Great Britain and Ireland |date=2003 |publisher=British Wildlife Publishing |location=Hook, Hampshire |isbn=0 9531399 1 3 |page=138 |ref=pw}}

Eggs are laid singly on the foodplant and the larvae are found from July to September.{{cite web |title=Netted Carpet factsheet |url=https://butterfly-conservation.org/sites/default/files/netted_carpet-psf.pdf |website=Butterfly Conservation |access-date=11 February 2021}} They feed at night on touch-me-not balsam (Impatiens noli-tangere), at first making holes in the leaves and later within the developing seedpods.{{cite book |last1=Henwood |first1=Barry |last2=Sterling |first2=Phil |last3=Lewington |first3=Richard |author3-link=Richard Lewington (artist) |title=Field Guide to the Caterpillars of Great Britain Ireland |date=2020 |publisher=Bloomsbury Publishing |location=London |isbn=978 1 4729 3358 4 |page=152}}{{cite web |last1=Kimber |first1=Ian |title=Netted Carpet Eustroma reticulata ([Denis & Schiffermüller], 1775) |url=https://ukmoths.org.uk/species/eustroma-reticulata/adult-3/ |website=UKmoths |access-date=11 February 2021}} In captivity they will feed on other balsams such as orange balsam (Impatiens capensis) but not on Indian balsam (Impatiens glandulifera) which is naturalised in the Lake District and out competes touch-me-not balsam.
Overwinters as a pupa on moist ground, near the foodplant, in an earthen cocoon.
Distribution
It is found in Europe, western and central Siberia, northern Mongolia, the Amur region, Khabarovsk, Primorsk, Sakhalin, Kurils, China, the Korean Peninsula and Japan.
;Great Britain
It is one of the rarest species of moth in Great Britain and is found in the Lake District and two sites in north Lancashire. The moth was close to near extinction in the 1980s and 1990s, but monitoring of nineteen sites shows that the moth is responding well to conservation management with more than 900% increase in abundance since 2000.{{cite web |last1=Kuliszewski |first1=Anya |title=September: the Netted Carpet moth |url=https://www.nationaltrust.org.uk/tarn-hows-and-coniston/features/september-the-netted-carpet-moth |website=National Trust |access-date=11 February 2021}}{{cite book |last1=Randle |first1=Zoe |last2=Evans-Hill |first2=Les J |last3=Parsons |first3=Mark S |last4=Tyner |first4=Angus |last5=Bourn |first5=Nigel A D |last6=Davis |first6=Tony |last7=Dennis |first7=Emily B |last8=O'Donnell |first8=Michael |last9=Prescott |first9=Tom |last10=Tordoff |first10=George |last11=Fox |first11=Richeard |title=Atlas Of Britain & Ireland's Larger Moths |date=2019 |publisher=Pices Publications |location=Newbury |isbn=978 1 874357 82 7 |page=106}} The moth was previousLy found in Wales; near Bala in 1930 and near Dolgellau in 1973.
