蜜蜂虱子Braula coeca是一种高度专业化的扁平无翅苍蝇，其整个成年生活都在成年蜜蜂身上度过。它通过在社会喂养（trophaltaxis）期间直接从蜜蜂那里偷取食物来喂养。Braula苍蝇有一个偏好，以侵扰蜂后。蚁后是殖民地中最受关注的个体，但尽管如此，工蚁仍然没有发现成年苍蝇。这是由于Braula拥有一个表皮碳氢化合物的轮廓，反映了他们的宿主蜂群，尽管双翅目和Hyplutera命令已经分开超过2.9亿年前。这种化学伪装是最有可能通过气味收购从蜜蜂主机，因为即使是小的殖民地特定的差异，在烯烃异构体模式中存在的蜜蜂也检测到Braula的配置文件。这一发现进一步支持了这样一种观点，即蜜蜂识别线索包含在其碳氢化合物特征的烯烃部分中，Braula利用这一点在其他敌对群体中保持未被检测到。
The bee louse Braula coeca is a highly specialised flattened, wingless fly that spends its entire adult life on adult honeybees. It feeds by stealing food directly from bees during social feeding (trophallaxis). The Braula fly has a preference to infest the honeybee queen. The queen is the most attended individual in the colony but despite this the adult flies remain undetected by the workers. This is due to Braula possessing a cuticular hydrocarbon profile that mirrors that of their host honeybee colony, despite Diptera and Hymenoptera orders having separated over 290 million years ago. This chemical camouflage is most likely through odour acquisition from the honeybee host since even small colony-specific differences in the alkene isomer patterns present in the honeybees were also detected in the Braula’s profile. This finding further supports the idea that the honeybee recognition cues are contained within the alkene part of their hydrocarbon profile and Braula exploit this to remain undetected within an otherwise hostile colony.
