This is the fate of my DIY bean bag that I made in June 2009.
After six months, the seed beetles invade it and burrow into the grain.
I opened the bag, threw away the infected bean, and refilled it with sand.
Seed beetles or bean weevils
Callosobruchus chinensis (Linnaeus), Bruchus chinensis (Bruchidae)
This was the first sign that I knew something sinister happened inside the bag. The bug came out of the bean bag through the cloth mesh when I was photographing the bird. That bug even crawled on my face!
The bugs jumped and flew out. This was a photograph on the mosaic floor.
I dumped the spoiled bean in my backyard on 26th November
Kacang Hijau - Mung Beans (Vigna radiate) - Oh!... different kind of BUG on that young leaf...
This is what happened after eleven days (7th December 2009).
Only a few beans are viable and grow, the rest are rotten like that black-coloured bean above.
... and here is another BUG (housefly) on the leaf.
