La Societe confirms that there are far fewer crane flies this autumn and warns that may eventually have an impact on the local bat and bird population.
La Société Guernesiaise says there are 'much lower numbers' number of crane flies this year.
The insects, also known as 'Daddy Longlegs' tend to come inside in the evenings in early autumn and are attracted to lights.
The local wildlife trust says long dry spells last summer destroyed the insect's natural habitat.
They usually live in long grass and their larvae eat the roots.
Adults don't tend to eat anything and are short lived, around two weeks, during which time they mate.
A spokesperson for La Société says if this population dip does not get resolved soon, it will impact the bats and birds that rely on them as a food source.
