Hummingbird hawk moths have been spotted in record numbers in the West Midlands this year, according to James Benwell from the Birmingham and Black Country Wildlife Trust. The species, which migrates from southern Europe and north Africa, is often mistaken for a small bird.
Other species, including ivy bees and the wasp spider, have also become more prevalent in the region. Ivy bees, first recorded in the UK in 2001, are slowly spreading north, while the wasp spider has been recorded in Worcestershire, Herefordshire, and Warwickshire.
The increase in sightings of these species coincides with warmer summer temperatures in parts of the West Midlands. Some migratory species, such as the clouded yellow butterfly, could become permanent residents if temperatures continue to rise, Mr Benwell suggested.
However, while some species are increasing, others are dwindling. Rosemary Winnall from the Wyre Forest Study Group noted that the small tortoiseshell butterfly and two-spot ladybird are now rarely seen.
