Scilly Could Be Barometer For Mainland Climate Change

Scilly could be a barometer for how climate change is affecting animal populations, including insects, on the mainland.

A report in The Times newspaper over the weekend reported that several species are changing their behaviour due to the milder average temperatures. This includes silver Y and yellow-line Quaker moths that are laying eggs into December.

But St Agnes resident and entomologist, Mike Hicks, says this has been happening for years in Scilly.

Mike has been recording moth species on the islands for around 15 years and often reports unusual species late in the season. He says some of them have been met with disbelief by experts up country.

Mike says moths can often lay eggs a second or even a third time in a year over here, which is highly unusual for the British Isles.

And species such as the white speck moth have been regular visitors from continental Europe in recent years.

Although it’s hard to draw direct parallels with the mainland, Mike thinks this could be a sign of what may happen there if temperatures continue to rise.
