ABSTRACT A number of species of Hymenoptera are associated with marine strandlines or wrack, where they are generally parasitoids of dipteran larvae and/or pupae. However, few records appear to exist of Hymenoptera associated with strandlines in New Zealand. We recorded the adult Hymenoptera obtained in 30 minute hand searches in strandlines at 36 sites at Christchurch and Banks Peninsula over the course of 3 years. Twenty-five species were recorded, consisting of four species of ants, one sawfly, one bee and 19 parasitoid wasps. The most commonly encountered species, in terms of both numbers collected and sites recorded, was Kleidotoma subantarcticana (Figitidae: Eucoilinae). Trichomalopsis sp. (Pteromalidae), two species of Spilomicrus (Diapriidae) and Trichopria sp. (Diapriidae) were also relatively widespread. There were no statistical differences in the number of Hymenoptera species recorded on sandy, shingle or boulder beaches on Banks Peninsula. Adult wasps were collected in all calendar months, although there was a decrease in occurrence in autumn and early winter. Hand searching proved a valuable method to obtain adult specimens of wasps for information on biogeography and seasonality. However, the rearing of wasps from different species of dipteran larvae or pupae is required to provide details of host species usage and attribute specific ecological functions of parasitoids within the strandline habitat.

与基督城和班克斯半岛的海洋海岸线有关的膜翅目

摘要许多膜翅目物种与海洋链或残骸有关，它们通常是双翅目幼虫和/或蛹的寄生生物。然而，在新西兰，与丝线相关的膜翅目似乎很少有记录。我们记录了在 3 年的时间里，在基督城和班克斯半岛的 36 个地点进行 30 分钟手动搜索获得的成虫膜翅目。记录了 25 种，包括 4 种蚂蚁、1 只锯蝇、1 只蜜蜂和 19 只寄生蜂。就收集的数量和记录的地点而言，最常见的物种是 Kleidotoma subantarcticana（Figitidae：Eucoilinae）。Trichomalopsis sp. (Pteromalidae)，两种 Spilomicrus (Diapriidae) 和 Trichopria sp。(Dipriidae) 也相对普遍。在班克斯半岛的沙滩、鹅卵石或巨石海滩上记录的膜翅目物种数量没有统计差异。尽管秋季和初冬的发生率有所减少，但在所有日历月都收集了成年黄蜂。手工搜索被证明是获取黄蜂成年标本以获取生物地理和季节性信息的一种有价值的方法。然而，需要从不同种类的双翅目幼虫或蛹中饲养黄蜂，以提供宿主物种使用的详细信息，并确定丝线栖息地内寄生蜂的特定生态功能。手工搜索被证明是获取黄蜂成年标本以获取生物地理和季节性信息的一种有价值的方法。然而，需要从不同种类的双翅目幼虫或蛹中饲养黄蜂，以提供宿主物种使用的详细信息，并确定线状栖息地内寄生蜂的特定生态功能。手工搜索被证明是获取黄蜂成年标本以获取生物地理和季节性信息的一种有价值的方法。然而，需要从不同种类的双翅目幼虫或蛹中饲养黄蜂，以提供宿主物种使用的详细信息，并确定丝线栖息地内寄生蜂的特定生态功能。
