花粉甲虫（Nitidulidae：Meligethinae）是欧洲最丰富的访花昆虫之一。虽然有些物种每年破坏数百万公顷的农作物，但许多物种的生物学却鲜为人知。我们评估的效用的细胞色素氧化酶1基因的797个碱基对的片段，以解决分子操作分类单位（MOTU）在750个成年花粉甲虫从花的63种植物在英国和欧洲大陆的采样。我们使用相同的基因座分析了重要的经济害虫--一些标本无法鉴定，因为含有它们的MOTU包括多个林奈物种的已发表序列，这表明保留了祖先单倍型多态性或已发表序列中的鉴定错误。超过90%的英国标本可被鉴定为B。埃涅阿斯。成株植物群丛aeneus被发现在分类学上比它们的幼虫要宽得多。UKB。aeneuspopulations之间的北方（最相似的斯堪的纳维亚半岛和波罗的海）和南方（最相似的欧洲大陆西部）的对比关系，在南方的人口增长的强烈签名。
Pollen beetles (Nitidulidae: Meligethinae) are among the most abundant flower-visiting insects in Europe. While some species damage millions of hectares of crops annually, the biology of many species is little known. We assessed the utility of a 797 base pair fragment of the cytochrome oxidase 1 gene to resolve molecular operational taxonomic units (MOTUs) in 750 adult pollen beetles sampled from flowers of 63 plant species sampled across the UK and continental Europe. We used the same locus to analyse region-scale patterns in population structure and demography in an economically important pest,Brassicogethes aeneus.We identified 44 Meligethinae at ∼2% divergence, 35 of which contained published sequences. A few specimens could not be identified because the MOTUs containing them included published sequences for multiple Linnaean species, suggesting either retention of ancestral haplotype polymorphism or identification errors in published sequences. Over 90% of UK specimens were identifiable asB. aeneus. Plant associations of adultB. aeneuswere found to be far wider taxonomically than for their larvae. UKB. aeneuspopulations showed contrasting affiliations between the north (most similar to Scandinavia and the Baltic) and south (most similar to western continental Europe), with strong signatures of population growth in the south.
