Along the way small Antophora bee found Me and kept Me a company for long time until I left Its territory. During the hot summer days these green-eyed solitary bees were fast fliers that collect nectar and pollen from flowers. Especially from Echium vulgare and various Lamiaceae that are common in this sandy area. (GPS: 48.54177, 17.25331) Blue sky, fine sand and endless concrete obstacles in between.
