Entomology (Study of Bugs)/please help identify.


My friends husband found this grub looking thing while cutting wood could you please tells us what kind of insect it becomes once it matures.

Dear Karrie -  This is a larva of a beetle in the family Buprestidae. The adult beetles are known as metallic wood-boring beetles (see http://tinyurl.com/nhhm4e for some examples) and the larvae often are called flat-headed wood-borers. I cannot tell you what species this might be, as larvae usually can be identified only by microscopic examination. I often find these myself when splitting firewood.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
