  1. Biometric variables were made on egg chorions for O. vulgaris and I. coindetii and on egg capsules for the rest of species. Temperature in °C. Swelling patterns for O. vulgaris were assessed on the basis of Ancova’s results; for the remaining species, the assessment was based on visual inspection of the published results. Temp. temperature, L egg length, l egg width, V egg volume, W egg wet weight. Swelling pattern: −+ a decreasing phase followed by an increasing phase; =+ constancy followed by an increasing phase; ++ a slow increasing phase followed by a fast increasing phase; = constancy all the time
