“…A. gigantea eggs can also be considered “supergiant” as compared with the eggs of other amphipod species ( Serra, 2003 ). Scanning electron microscopy revealed that the eggshell of A. gigantea was composed of a fibrillar exochorion (Figure 1D ) and a porous endochorion layer ( Figures 1D,E ), similar to the eggshell structure of the fruit flies Ceratitis capitata ( Margaritis, 1985 ) and Rhagoletis cerasi ( Mouzaki & Margaritis, 1991 ). The mean diameter of the pores of the endochorion was >10 μm, with the largest diameter up to 20 μm ( Figure 1F ), similar to the perforations of the alveolar layer of the eggshell of Triops cancriformis, a crustacean surviving in temporary freshwater pools ( Tommasini et al, 1989 ), but much larger than that of three species of neotropical Eulimnadia (Crustacea: Branchiopoda: Spinicaudata) ( Rabet et al, 2012 ).…”

“…As the follicle cells secrete the main components of vitelline membrane, the microvilli carry them to the surface of the oocyte to form the vitelline membrane. In stoneflies, the vitelline membrane is formed by electrondense fibrillar material deposited around microvilli (Rosciszewska, 1995) and the innermost fibrous layer may have water-proofing function (Mouzaki and Margaritis, 1991). In Panorpa, the vitelline membrane might be formed by the compacted protein, the product of the annular rough endoplasmic reticulum.…”

“…Το εξωχόριο αποτελείται από ινίδια πάχους 40 Â, που τείνουν να προσανατολισθούν παράλληλα με την επιφάνεια του ωοκυττάρου. Το χόριο των διπτέρων των οικογενειών Drosophilidae, Calliphoridae, Glossinidae και Terphitidae εμφανίζει, σε γενικές γραμμές, την ίδια ακτινωτή πολυπλοκότητα με το χόριο του διπτέρου D. melanogaster (Margaritis, 1985a, 1985b, Mouzaki and Margaritis, 1991a, 1991b. To χόριο των διπτέρων της οικογένειας Muscidae εμφανίζει δύο ή περισσότερα ενδοχόρια ενώ το χόριο των διπτέρων της οικογένειας Culicidae εμφανίζει δύο διακριτές ζώνες πάνω από την βιτελλινική μεμβράνη : το ενδοχόριο και το εξωχόριο (Margaritis, 1985a).…”
