Summary.Adult tiger moths exhibit a wide range of palatabilities to the insectivorous big brown bat Eptesicus fuscus. Much of this variation is due to plant allelochemics ingested and sequestered from their larval food. By using a comparative approach involving 15 species from six tribes and two subfamilies of the Arctiidae we have shown that tiger moths feeding on cardiac glycoside-containing plants often contain highly effective natural feeding deterrents. Feeding on pyrrolizidine alkaloid… 
Feeding on Host Plants with Different Concentrations and Structures of Pyrrolizidine Alkaloids Impacts the Chemical-Defense Effectiveness of a Specialist Herbivore
TLDR
The protection against the spider was more effective in adults whose larvae fed on seeds, which had a higher PA concentration than leaves, and the results are partially explained by host plant phylogeny, since PAs of the host plants do have a phylogenetic signal which is reflected in the adult defense.
HPLC-MS Analysis of Lichen-Derived Metabolites in the Life Stages of Crambidia cephalica (Grote & Robinson)
TLDR
Results provide evidence that multiple lichen-derived metabolites are sequestered by C. cephalica; some metabolites are retained through adulthood, and others are lost or modified in earlier life stages.
A preliminary molecular phylogenetic assessment of the lichen moths (Lepidoptera: Erebidae: Arctiinae: Lithosiini) with comments on palatability and chemical sequestration
TLDR
The results of this study and prior reports in the literature of chemical sequestration and unpalatability are plotted onto the resulting Bayesian inference phylogeny to examine the evolution of chemical defence within Lithosiini.
Physiological adaptations of specialized insects to host plant cardenolides
TLDR
It is concluded that D. nerii possesses adaptations which enable it to feed on a cardenolide rich diet other than those previously described in cardenOLide specialised insects, and the discussed other potential resistance mechanisms are discussed.
The adaptive function of tiger moth clicks against echolocating bats: an experimental and synthetic approach
TLDR
These findings support the hypotheses that the clicks of arctiid moths are both an active defence (through echolocation disruption) and a reliable indicator of chemical defence against aerial-hawking bats.

Fate of Host-Plant Iridoid Glycosides in Lepidopteran Larvae of Nymphalidae and Arcthdae
TLDR
The ability of larvae of six lepidopteran species to sequester iridoid glycosides was compared and it was found that, as expected, J. coenia larvae did contain iridoids, whereas V. cardui larvae did not.
Advances in Insect Chemical Ecology: A quest for alkaloids: the curious relationship between tiger moths and plants containing pyrrolizidine alkaloids
TLDR
The members of the family Arctiidae, which numbers over 11 000 species, are often brilliantly colored and may have iridescent blue and green, or even pearly white, coloration, which can be considered aposematic when individuals rest conspicuously on green vegetation.
Cardenolide sequestration by the dogbane tiger moth (Cycnia tenera; Arctiidae)
TLDR
Thin-layer chromatography confirmed that each individual cardenolide visualized in the adult moths reared on the former host plant corresponds to one present in the plant, thus demonstrating that the insects' cardanolides are indeed derived from the larval food.
Attraction of Lepidoptera to Plants Containing Pyrrolizidine Alkaloids
TLDR
Preliminary observations of populations of Ithomiinae and Danaus reveal that the presence of naturally occurring PA-sources are a major factor in determining population distribution, abundance, and reproductive behavior.
Unpalatability of the pyrrolizidine alkaloid-containing moth, Utetheisa ornatrix, and its larva, to wolf spiders
TLDR
Experiments demonstrating that Utetheisa, as larvae and adults, are protected against wolf spiders are reported.
Chemical defense against predation in an insect egg.
TLDR
Each cluster in nature can be expected to range widely in palatability, so to check each cluster for acceptability must be adaptive for the larva, just as it must be adapted for Utetheisa to lay its eggs in large clusters and to apportion alkaloid evenly among eggs of a cluster.
Sequestration of pyrrolizidine alkaloids in several arctiid moths (Lepidoptera: Arctiidae)
TLDR
The larval integument figures as the main storage site for resorbed alkaloids; only minor amounts of alkaloid could be found in the meconium and the exuviae of this species.
Precopulatory sexual interaction in an arctiid moth (Utetheisa ornatrix): Role of a pheromone derived from dietary alkaloids
TLDR
It is proposed that in addition to signalling male presence to the female, hydroxydanaidal may provide the means whereby the female assesses the alkaloid content of the male and therefore his degree of chemical protectedness.
Are Insect-Synthesized Retronecine Esters (Creatonotines) the Precursors of the Male Courtship Pheromone in the Arctiid Moth Estigmene acrea?
TLDR
It is suggested that the creatonotines are direct pheromone precursors in E. acrea and may represent a general mechanism of hydroxydanaidal formation from diverse macrocyclic PAs in arctiids.
