Figure 4. from: Melampyrum sylvaticum as a pre-diapause host plant of the scarce fritillary (Euphydryas maturna) in Finland - Biodiversity Data Journal 3: e5610 (17 July 2015) https://doi.org/10.3897/BDJ.3.e5610
Figure 4. - Euphydryas maturna habitat in a commercial, thinned pine-dominated forest with ca. 30-year old trees, and in a clear-cut edge. This kind of forest habitat is probably suitable after thinning for several years, but longer than spruce-dominated forests (Fig. 3). Also, edge habitats in these relatively dry habitats overgrow somewhat slower than in moister edges (Fig. 2).

Figure 5. - Powerline habitat of Euphydryas maturna. Vegetation under powerlines is kept open continuously, so powerline habitats may function both as breeding places and dispersal corridors.

Oviposition trials of Euphydryas phaeton on Plantago lanceolata
<p>Understanding the circumstances under which insect herbivores will adopt a novel host plant is a longstanding question in basic and applied ecology. Though there has been ample study of regional differences in host preference across numerous insect herbivores, the extent to which intraspecific variation in plant species shape these patterns is relatively less well known. In parts of its range the Baltimore checkerspot<em> Euphydryas phaeton</em> uses English plantain <em>Plantago lanceolata</em>, a novel host plant, in addition to its native host, White turtlehead <em>Chelone galbra</em>. We offered female butterflies from each region the non-native host lpant sourced from both regions and compared their oviposition behavior. The non-native host was near universally rejected by butterflies in the region where only the native plant is used. In the region where both hosts are used, plants from that same region were preferred relative to plants from the other region. This suggests that regional variation in host plant use by an insect depends on intraspecific variation in both species in the interaction.</p>

Strong isolation by distance among local populations of an endangered butterfly species (Euphydryas aurinia)
<p>The marsh fritillary (<i>Euphydryas aurinia</i>) is a critically endangered butterfly species in Denmark known to be particularly vulnerable to habitat fragmentation due to its poor dispersal capacity. We identified and genotyped 318 novel SNP loci across 273 individuals obtained from 10 small and fragmented populations in Denmark using a genotyping-by-sequencing (GBS) approach to investigate its population genetic structure. Our results showed clear genetic substructuring and highly significant population differentiation based on genetic divergence (F<sub>ST</sub>) among the 10 populations. The populations clustered in three overall clusters and due to further substructuring among these, it was possible to clearly distinguish six clusters in total. We found highly significant deviations from Hardy-Weinberg equilibrium due to heterozygote deficiency within every population investigated which indicates substructuring and/or inbreeding (due to mating among closely related individuals). The stringent filtering procedure that we have applied to our genotype quality could have overestimated the heterozygote deficiency and the degree of substructuring of our clusters but is allowing relative comparisons of the genetic parameters among clusters. Genetic divergence increased significantly with geographic distance, suggesting limited gene flow at spatial scales comparable to the dispersal distance of individual butterflies and strong isolation by distance. Altogether, our results clearly indicate that the marsh fritillary populations are genetically isolated. Further, our results highlight that the relevant spatial scale for conservation of rare, low mobile species may be smaller than previously anticipated.</p>

Data from: Melampyrum sylvaticum as a pre-diapause host plant of the scarce fritillary (Euphydryas maturna) in Finland
Background: The scarce fritillary Euphydryas (Hypodryas) maturna (L.) is included in the Habitats Directive's Annexes II and IV(a). Therefore, it is crucially important to be able to define the habitat and breeding places of E. maturna in a correct and unbiased way. New information: Data on a previously unknown pre-diapause main host plant, the small cow-wheat (Melampyrum sylvaticum L.), of Euphydryas maturna in Finland is presented.
