  • Gryllacridinae

  • Lezininae

Gryllacrididae are a family of non-jumping insects in the suborder Ensifera occurring worldwide, known commonly as leaf-rolling crickets or raspy crickets. The family historically has been broadly defined to include what are presently several other families, such as Stenopelmatidae ("Jerusalem crickets") and Rhaphidophoridae ("camel crickets"),[1] now considered separate. As presently defined, the family contains two subfamilies, with the vast majority (over 90 genera containing over 600 species) in the subfamily Gryllacridinae.[2] The remaining subfamily, Lezininae, contains only a single genus with 12 described species.[3][4] They are commonly wingless and nocturnal. In the daytime, most species rest in shelters made from folded leaves sewn with silk. Some species use silk to burrow in sand, earth or wood.[5] Raspy crickets evolved the ability to produce silk independently from other insects, but their silk has many convergent features to silkworm silk, being made of long, repetitive proteins with an extended beta-sheet structure.[6]


These are predators of other insects and spiders.[7]

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

How to make file upload 'Required' in Contact Form 7? I have a Contact Form 7 form on my Wordpress website and I have specified that the file upload is mandatory by putting a * , however the users are able to submit the form without file upload. * Relevant Contact Form 7 form is given below: <div class="filelink">[file* AddanImage filetypes:gif|png|jpg|jpeg]</div> How do I write the Contact Form 7 code or add a validation perhaps so that the users are not able to submit the form without uploading an image? Any hints/help/guidance is highly appreciated. Have you check doc - contactform7.com/file-uploading-and-attachment – Mukesh Panchal Jun 30 at 8:38 @MukeshPanchal I have and the code complies with the documentation – Hamza Ahmad Jul 1 at 10:44

amazon EC2 - How to make wp-config.php to writable?

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. Some of the errors: "A definition of a siteurl or homeurl was detected in your wp-config.php, but the file is not writable. Set your wp-config.php to writable and reload this page." From W3 total Cache: Please add the error messages you get back. – Damien Feb 8 '17 at 12:42 one is: " A definition of a siteurl or homeurl was detected in your wp-config.php, but the file is not writable. Set your wp-config.php to writable and reload this page."
