Cuckoo spit/spittlebug foam on vegetation is innocent. Please depart it alone.


I’m normally delighted to see Eire’s Wildlife featured within the media — however a current article printed within the Gardening part of the RSVP Journal web site has me lower than thrilled.

Cuckoo Spit and Frog Hoppers - Spittle Bugs are not harmful

The article in query sensationalises the connection between frog-hoppers/spittle bugs (their American identify) and a bacterial plant illness referred to as Xylella fastidiosa. Sure, in areas the place Xylella happens, sap-sucking bugs like frog-hoppers typically turn into vectors by means of which the pathogen spreads to different close by vegetation, nevertheless, Xylella is NOT CAUSED by the insect, and the frothy spittle so frequent on vegetation all through the Irish countryside in early summer time IS NOT an indication of illness. The truth is, it’s a completely regular a part of a wholesome Irish ecosystem.

We now have by no means had a confirmed circumstances of Xyllela right here in Eire, they usually have recorded none up to now within the UK both. For now at the very least, it merely doesn’t happen right here.

The RSVP Journal article latches on to a legit name for info from scientist within the UK, and twists it into one thing altogether extra sinister. All of the scientists are asking for is for the general public to submit information of cuckoo spit and grownup frog-hoppers, serving to them to map their distribution. That information will assist them make extra knowledgeable selections on how greatest to reply IF Xylella ever does arrive.

Simply to be 100% clear right here: these scientists are not suggesting cuckoo spit is in any method dangerous, they’re not calling for anybody to regulate frog hoppers or eradicate cuckoo spit of their gardens or wherever else. They’re simply gathering information to higher perceive their distribution.

To summarise:

  • Xylella fastidiosa has by no means been recorded in Eire
  • Frog Hoppers / Spittle Bugs are widespread, frequent native Irish bugs
  • They DO NOT trigger illness in vegetation (though the place Xylella is current they’ll unfold it)
  • Cuckoo Spit is NOT A SIGN OF DISEASE: it’s a regular a part of a wholesome, functioning Irish ecosystem
  • There is no such thing as a viable purpose to take away cuckoo spit from vegetation in your backyard

Discover out extra concerning the fascinating Widespread Frog Hopper right here. For those who’re excited by discovering out extra concerning the scenario surrounding Xylella, right here’s a complete overview of Xylella and frog-hoppers within the UK that’s effectively offered and fact-based.

The risks of poor reporting in a Biodiversity Disaster

No one is denying that Xylella is a critical illness, and has brought on devastation in components of mainland Europe (significantly to Italian olive groves). Measures to regulate and limit the unfold of the micro organism that causes the illness are fully warranted. What’s unwarranted is equivocal reporting that misrepresents the information, casting a innocent constituent of our native biodiversity because the villain in a contrived and appallingly inaccurate narrative.

Wildlife isn’t any stranger to being solid because the scapegoat for human-induced issues within the pure world, however amidst a biodiversity disaster, articles just like the RSVP one, that sensationalise danger, foster suspicion and demonise a local species, will be extremely damaging. We’ve been receiving emails and messages since this text went out from folks asking how they’ll eradicate cuckoo spit from their backyard vegetation.

The reply, in fact, is you don’t have to do something. Because the BBC Gardener’s World web site advises “It’s greatest to depart the froghoppers to get on with being froghoppers.”
