TL;DR: It is suggested that lichenivorous lepidopteran species may have different adaptations, such as dietary mixing to receive nutrients in optimal proportions or compensatory feeding ability to ensure the maximal growth efficiency on a suboptimal host.
Abstract: Summary
1
We compared the larval host preference of four lichenivorous Eilema (Lepidoptera, Arctiidae) species on four common epiphytic lichen species including Hypogymnia physodes, Melanelia exasperata, Vulpicida pinastri and Xanthoria parietina. Survival and growth of larvae on different species were monitored and correlation to qualitative and quantitative variation in lichen secondary compounds was analysed.
2
All moth species preferred M. exasperata, which does not contain polyphenolic substances, over other lichens, but also foraged on other lichens in the food preference experiment. All larvae reared on V. pinastri and H. physodes died during the growth and survival experiment. Survival of larvae on X. parietina and M. exasperata were equal. Larvae grew faster and and bigger on M. exasperata than on other lichens.
3
Consumption and utilization measurements also revealed that M. exasperata was of the highest quality, although the relative consumption rate was highest on X. parietina. Our results indicate that different secondary chemicals have different effect against lichenivores or that larvae are either well adapted to certain chemicals or that these chemicals may have other roles than antiherbivore function for lichens.

It is suggested that lichenivorous lepidopteran species may have different adaptations, such as dietary mixing to receive nutrients in optimal proportions or compensatory feeding ability to ensure the maximal growth efficiency on a suboptimal host.

TL;DR: The prevalence of all isolates in their hosts was low and ranged from 1.0% to 5.3%.
Abstract: We examined 34 lepidopteran species belonging to 12 families to determine presence and prevalence of microsporidian pathogens. The insects were collected from May 2009 to July 2012 from 44 sites in Bulgaria. Nosema species were isolated from Archips xylosteana, Tortrix viridana, Operophtera brumata, Orthosia cerasi, and Orthosia cruda. Endoreticulatus sp. was isolated from Eilema complana. The prevalence of all isolates in their hosts was low and ranged from 1.0% to 5.3%. Phylogenetic analyses of the new isolates based on SSU rDNA are presented.
TL;DR: This first work on the Heterocera the author gives some results of researches on the Lepidopterofauna, carried out in Apulia and Lucania during 1967-77, and describes the main localities explored.
Abstract: CONTRIBUTIONS TO THE KNOWLEDGE OF LEPIDOPTERA IN SOURTHERN ITALY IV. Heterocera (Bombyces ET Sphinges) OF APULIA AND LUCANIA By this first work on the Heterocera the author gives some results of researches on the Lepidopterofauna, carried out in Apulia and Lucania during 1967-77. In the first part are described the main localities explored, except the ones already dealt with in a former paper on the Rhopalocera. In the second part the collected species are listed with some data upon geonemy, frequency and, in the case of agricultural and foresta! interesting species, with regard to the damages they have clone. There are also listed the species mentioned by other authors for Apulia and Lucania, and not collected during the present researches. The species l i s t follows FoRSTER & WoHLFARTH's terminology , w i t h some necessary revisions and the addition of species since now uncollected in Centrai Europe. 182 species are listed (45,8% of the species known as living in Continental ltaly). Eilema rungsi Toulg. is reported for the first time in Europe; Orgyia ericae Germ., Notodonta tiefi Bartel and Hypopta thrips Hb. as new in Italy; Penestoglossa dardoinella Mill. are mentioned for the first time in Continental Italy; Eilema depressa Esp. and Celama subchlamydula Stgr. are mentioned for the first time in Centrai and Southern Italy . Also in Southern Italy are mentioned for the first time: Nola cucullatella L., Ocneria prolai Htg., Nudaria mundana L., Apaidia rufeola Rbr., Eilema unita Schifi., Eilema lurideola Zinck., Chelis maculosa Germ., Rhyparia purpurata L., Hyphoraia testu- dinaria Fourc., Pelosia muscerda Hfn., Pelosia obtusa H.-S., Sphinx ligustri L., Hemaris t i t y u s L., Malacosoma castrensis L., Malacosoma franconica Esp., T richiura crataegi L., Macrothylacia rubi L., Acanthopsyche atra L., Amictoides sera Wisk., Phalacropteryx api- formis Rossi, Fumea crassiorelia Brd., Pryropteron chrysidiformis Esp., Hypopta caestrum Hb., Phragmatecia castaneae Hb. Most of the other species here reported are not yet mentioned in Apulia or Lucania.
