- [Pinaceae:] Larix decidua (Europäische Lärche)
Razowski (2001: 90) meldete knapp: "unter R[inde]; Abies (Pinaceae)."
Hancock et al. (2015: 187) schrieben: "Ovum. Laid in June on or in the bark of firs (Abies sp.), possibly also utilizes Pinus sp. (Razowski, 2003)." Konkrete Hinweise auf oder gar Funde an Pinus scheint es aber nicht zu geben.
Rudolf Bryner fand seine Raupen in der Schweiz (s.o.) an Rinden-Verletzungsstellen junger Fichten (Picea abies). Warum diese Pflanze in den oben genannten Arbeiten nicht angesprochen wird, ist unverständlich, denn schon Buhl et al. (1984) hatten aus Dänemark berichtet: "Numerous larvae of Cydia indivisa (Danil.) have been found in Funen (F) and some observations on their biology are reported. The main host tree was Picea abies but also Picea sithensis [sic!] was infected. The trees were 15-40 years old, those of 20-30 years of age apparently being preferred. It is easiest to find the species in plantings that have been thinned out. The larvae infect resin-exuding wounds on the sunny side of the trees, and infections are recognizable by frass piles coming out from the margins of the wounds from late March to early May. The larva is grey-white. The head is brown with a darker V-shaped mark. The prothoracic plate, which is divided in the middle, is brown. The whole larva is hairy. It is somewhat difficult to bring the larvae safely home as they easily become smeared with the resin when the galleries are disturbed. In addition the larvae are frequently parasitized. It is therefore most profitable to collect the pupae, which may be found from early May to early June and are located in a white web in the area of resin. Larvae of the muscid fly Phaonia czerny Hennig, 1963 is reported as predators on C. indivisa larvae." Lyneborg (1987) - auf der Suche nach Parasitoiden der Raupen - bestätigt dies.
Szabóky & Buschmann (2010: 198) berichteten aus Ungarn (Sopron, Muck (Restaurant Moha)): "On 17 March 2009 Cydia milleniana (ADAMCZEWSKI, 1967) specimens were collected from larch (Larix decidua) (leg. CS. SZABÓKY & GY. CSÓKA). A web with light brown traces of frass and droppings was hanging from the one year old cones. Nearly one hundred “webby” cones were collected and put into breeding cages. On the first days of May ichneumon wasps emerged from the cones, then later a few Cydia indivisa specimens. This was followed by collecting on the terrace of the Restaurant Moha, with the help of a 125W Hgl bulb and a white sheet (leg. CS. SZABÓKY). Two roughly 80 year old larch trees stood 20 meters from the collecting place, with their branches full of cones. Thirty minutes after dusk the first C. indivisa arrived, and a further six specimens until 11 pm. Rain started before midnight terminating the collecting with a storm. Until now, the known foodplant of C. indivisa were firs (Abies). It is worth mentioning that both firs and larches have erecting cones."
Demnach lebt die Raupe also nicht nur an Rinde, sondern auch um junge Zapfen von Koniferen.
