Kerriidae is a family of scale insects, commonly known as lac insects or lac scales. Some members of the genera Metatachardia, Tachardiella, Austrotacharidia, Afrotachardina, Tachardina, and Kerria are raised for commercial purposes, though the most commonly cultivated species is Kerria lacca. These insects secrete a waxy resin that is harvested and converted commercially into lac and shellac, used in various dyes, cosmetics, food glazes, wood finishing varnishes and polishes.


Species include:



  • Kerria lacca - true lac scale


  • Paratachardina decorella - rosette lac scale


  • Paratachardina pseudolobata - lobate lac scale

How to make file upload 'Required' in Contact Form 7?

amazon EC2 - How to make wp-config.php to writable? I'm using Amazon EC2 with Bitnami wordpress. I recently tried to use plugins, they install and activate well, but there are still errors. Those errors look like permission errors. Also, perhaps, how to make the whole wordpress directory writable? I'm only accessing through SSH.
