Eggshells of Australian, Gomphidae: Plastron respiration in eggs of stream-dwelling Odonata (Anisoptera)
Eggshells of 10 Austrogomphus , 3 Antipodogomphus and 1 Hemigomphus species (Gomphinae) were examined using scanning electron microscopy. In 9 Austrogomphus spp. the outermost eggshell layers were found to carry a field of prominent pillars supporting a gelatinous outer chorion above the general egg...

description | Eggshells of 10 Austrogomphus , 3 Antipodogomphus and 1 Hemigomphus species (Gomphinae) were examined using scanning electron microscopy. In 9 Austrogomphus spp. the outermost eggshell layers were found to carry a field of prominent pillars supporting a gelatinous outer chorion above the general egg surface. Eggs of Antipodogomphus were similar but with pustulate projections in place of pillars. Eggs of 1 Austrogomphus and 1 Hemigomphus sp. did not carry such structures. The structures are interpreted as respiratory plastrons. |
