Striped Hawk-moth (Hyles livornica) is an uncommon migrant moth in Devon, with 72 sightings on the Devon Moth Group database, the most recent from 2015. This visitor from warmer parts of continental Europe is usually seen here in the summer. However, the warm southerly winds that brought Saharan dust to our shores last week, also encouraged some early migrants northwards! Jayne Wraxall found and photographed this one on the side of the road at Exwick on 3 April.
2015 is shaping up to be a record year for moth immigration into Great Britain. Although the peak time of year for moth arrivals is autumn, there have already been substantial influxes from southern Europe.
Three species, in particular, have featured prominently both here in Devon and across the south during May and June; Bordered Straw (Heliothis peltigera), Small Mottled Willow (Spodoptera exigua) and Striped Hawk-moth (Hyles livornica). More recently, Small Marbled (Eublemma parva) has arrived in (relative) abundance. None are rare visitors, but the numbers seen so far this year, particularly of the first two species, are likely to break previous records.
Many moth recorders in Devon will have recorded at least one Bordered Straw and Small Mottled Willow this year, but only a lucky few have seen the stunning Striped Hawk-moth. One recorder, Mark Marshall, has had a great run of fortune, recording two Striped Hawk-moths and an Orache Moth (Trachea atriplicis), a scarce immigrant, at his home near Blackawton in the South Hams.
There’s little sign of an end to the migrant activity so keep recording and good luck!
