Eriogaster catax (Linnaeus, 1758) and E. lanestris (Linnaeus, 1758) are two related species in the family Lasiocampidae with decreasing distribution areas and extremely isolated populations, thus being vulnerable to numerous threats, particularly human impact. Until presently, the biological and ecological studies regarding the species in question are scarce, particularly for E. catax, a species protected through Annexes II and IV of the Council Directive 92/43/EEC, Annex II of the Bern Convention and Law no. 49/2011 in Romania. Taking into account the importance of the E. catax species and the insufficient information reported on the ecological need of the species, a highly detailed analysis at an ultrastructural level could provide valuable information. The primitive aspect of the wings explained the weak distribution of adults. The different flight period of adults and egg laying season were reflected on the structure, adherence and size of eggs. Also, the structure of the fibers was correlated with the different ways in which E. catax and E. lanestris use the nest.

Keywords: Eriogaster catax, E. lanestris, oviposition strategy, ecological niche.
