According to butterfly expert and organizer of the initiative Uģis Piterāns, the aim is to fill in the gaps in current knowledge about Latvia's butterfly population at a time fo year when they are very visible.
Spottings can be recorded at the nature website dabasdati.lv..
As Piterāns told LTV's 'Morning panorama' news show, contributing is easy.
"You do not necessarily need professional expertise, it is enough to use what you have at hand - go to the meadow, take pictures and upload them to the website," he said.
If you don't know the exact species yourself, don't worry - someone else will provide an identification. Latvia is believed to be home to around 120 species of butterfly, so it will be interesting to see how many are spotted during the survey.
"Butterfly watching is at its best during these long days. In the mornings and evenings butterflies are at rest, but during the day when they feed, it is possible to stalk them and catch them for a moment in a picture," Piterāns explained.
