A total of 7,544 spittlebugs, 2,936 females and 4,608 males collected from three different types of deciduous forest were analysed. Four non-melanic-populi (POP), typicus (TYP), trilineatus (TRI), vittatus (VIT), and four melanic-marginellus (MAR), lateralis (LAT), flavicollis (FLA), leueocephalus (LCE) - phenotypes expressed by six different alleles were determined. Melanic phenotypes were limited to the female sex only, moreover the melanic O group was not found in the 29 different populations sampled. POP+TYP were predominant phenotypes in the pooled samples (94%). The combined melanics and TRI+VIT were present at equal proportions (3% each). The average sample size for 40 sampling sessions was (Mean S.E.) 187.1 +/- 14.3 (range: 31-361).eninfo:eu-repo/semantics/closedAccessPolymorphismMelanismHomopteraPhilaenus SpumariusTurkeyColor Pattern PolymorphismL Homoptera CercopidaeBalanced PolymorphismAphrophoridae PopulationsMeadow SpittlebugHemipteraEnglandDriftArticle5012534Q4WOS:000225203700003
