Ilias Antonopoulos

I share my knowledge and experience about gardening, growing vegetables, trees, flowers and recycling. Every day I learn new things. I am experiencing what Greek philosopher Socrates said: "all I know is that I know nothing" ("Εν Οίδα, Ότι Ουδέν Οίδα"). I perceive my self as always a student. I created kalliergo.gr back in 2010, charmed by the plants magical world. I am a Biomedical Engineer, holding a MSc degree on E-Business. For a living I help businesses to grow online. I am not an agronomist but wish I had also a degree on agronomy. I hope that you will find interesting and helpful information on KALLIERGO.

Firefly (insect)

As a child I often saw insects called fireflies or “kolofoties – κολοφωτιές” as they were called by the older ones.
