Abstract

The complete life history of the kleptoparasitic ‘sundew flower fly’, Toxomerus basalis, is presented and illustrated. Adults of this species are photographed alive for the first time, including video recordings of larval and adult behaviour. Adult flies of both sexes visit Drosera (sundews) and show territorial behaviour around the plants, avoiding the dangerous sticky traps and demonstrating recognition of their larval host plant. Females lay eggs directly on non-sticky parts of the Drosera host plants, such as on the lower surface of the leaves and flower stalks, but apparently also on other plants growing in close proximity with the sundews.

被引诱进食，而不是被引诱进食——关于基底弓形虫的生物学（Walker，1836），一种盗窃寄生的“向日葵蝇”（Diptera：Syrphidae）

介绍并举例说明了盗窃寄生“向日葵蝇”Toxomerus basiris的完整生活史。该物种的成虫首次被拍到活着的照片，包括幼虫和成虫行为的视频记录。两性成年苍蝇都会造访Drosera（Sundows），并在植物周围表现出领地行为，避开危险的粘性陷阱，并表现出对其幼虫宿主植物的识别。雌性直接在Drosera寄主植物的非粘性部分产卵，例如在叶子和花茎的下表面，但显然也在生长在离向日葵很近的其他植物上产卵。

期刊介绍： Journal of Tropical Ecology aims to address topics of general relevance and significance to tropical ecology. This includes sub-disciplines of ecology, such as conservation biology, evolutionary ecology, marine ecology, microbial ecology, molecular ecology, quantitative ecology, etc. Studies in the field of tropical medicine, specifically where it involves ecological surroundings (e.g., zoonotic or vector-borne disease ecology), are also suitable. We also welcome methods papers, provided that the techniques are well-described and are of broad general utility. Please keep in mind that studies focused on specific geographic regions or on particular taxa will be better suited to more specialist journals. In order to help the editors make their decision, in your cover letter please address the specific hypothesis your study addresses, and how the results will interest the broad field of tropical ecology. While we will consider purely descriptive studies of outstanding general interest, the case for them should be made in the cover letter.
