  1. Non-native species can be a real problem as they often have no natural enemies. Numbers can quickly expand, upsetting the balance of nature. But the Harlequin has quickly endeared itself with the public, because of its attractive appearance and its habit of overwintering in people’s homes. Last year it really impressed me by developing a taste for asparagus beetle grubs. Left unchecked, these grubs can devastate the asparagus crop on my allotment each Spring. Until now the only effective control method has been squashing them by hand. The Harlequins ate most of the asparagus beetle grubs in quick time. An interesting case of one introduced species becoming a predator on another!

    • That’s fascinating – thanks for sharing! I’m convinced that many of the solutions we seek for problems already exist in nature. I think sometimes we just have to watch and see what happens.

      • “Rupert,

        I agree that\’s true in some circumstances. Horse chestnut leaf miner is a good example of an alien introduction everyone was concerned about a few years back, ruining our confer trees by turning their leaves brown. One horse chestnut near me was felled as it was deemed unsightly. The moth spread like the plague and was all over England within three years of being spotted. But now nature is rebalancing and I\’ve received several reports of tits, particularly long tailed tits hoovering up the moths.

        On the other and we have species such as Oak Processionary Moth, established in London a few years back which are potentially hazardous to humans and oak trees which should be controlled. The 2 key questions are whether control is really necessary and how it is carried out – spraying to eradicate one species can harm a who.e lot of native species. Happy to discuss
