Fig. 3From: The emergence of ecotypes in a parasitoid wasp: a case of incipient sympatric speciation in Hymenoptera?Number of pupae of Lucilia sericata carrion flies parasitized by Nasonia vitripennis wasps (A) and offspring emerging from these pupae (B). Wasps were collected in bird nests (yellow, n = 90) or next to carrion (blue, n = 90). The box and whisker plots show minimum, maximum, 1st and 3rd quartile, median and mean as asterisk. **: significant difference at p < 0.01 (Mann–Whitney U-test)Back to article page
