AB  - Like many animals, firebugs (Hemiptera, Pyrrhocoridae) rely on behavioural 
      adaptations to successfully endow their offspring with microbial mutualists. To 
      transmit the nutritionally beneficial Coriobacteriaceae symbionts, female 
      firebugs smear egg surfaces with symbiont-containing faecal droplets that are 
      subsequently ingested by newly hatched nymphs through active probing to initiate 
      infection. Alternatively, the symbionts can be acquired horizontally through 
      contact with faeces of infected conspecifics. Here, we report that these 
      adaptations ensuring successful transmission of bacterial symbionts among 
      firebugs are exploited by the specialized trypanosomatid parasite Leptomonas 
      pyrrhocoris. Using comparative transcriptomics, fluorescence in situ 
      hybridization (FISH) and controlled bioassays, we demonstrate that the 
      transmission cycle of L. pyrrhocoris mirrors that of the bacterial mutualists, 
      with high efficiency for both vertical and horizontal transmission. This 
      indicates that the parasite capitalizes on pre-existing behavioural adaptations 
      (egg smearing and probing) to facilitate its own transfer within host 
      populations, adaptations that likely evolved to initiate and maintain an 
      association with beneficial gut symbionts. Thus, the transmission of mutualistic 
      microbes across host generations can entail a significant risk of co-transmitting 
      pathogens or parasites, thereby exerting selective pressures on the host to 
      evolve more specific mechanisms of transfer.
