Ticks, a creature that can spread a harmful infection to humans, have emerged early due to warm weather, Mountaineering Scotland has warned.
The outdoor pursuits enthusiasts organisation said they had been found in locations across Scotland, including in Aberdeenshire.
Lyme disease, a bacterial infection, can be spread to humans by infected tick bites.
The arthropods usually start to emerge in March.
Mountaineering Scotland, which regularly issues warnings about the pests, has sought further reports of ticks from its members.
People are most likely to come across sheep ticks, which feed on mammals such as deer and also birds, in open spaces with long grass or bracken.
