We went to an area near the foot of Mt Tsukuba and after an hour or so, found a spot with a few fireflies. I was quite surprised because they were really small! My friend's husband caught one and I held it - it was less than 1cm long. I thought they would be 2 or 3cm :)
The fireflies were on some plants growing in the middle of a small river. I heard they only live in clean water where a certain kind of freshwater shellfish live. Firefly larvae eat the shellfish. Nowadays it is really hard to find such clean water as farmers use pesticides and herbicides. It is such a pity that we are destroying our own environment.
This final picture is one I found on the Internet and it shows you what a firefly looks like in the light. I tried to get a picture of the one we caught, but he moved too quickly!
