Can you identify this bug for us. It is about 3/4 inch long and it”s tail lights up a neon green. We have hundreds of them in the yard and this is the first year that we have seen them. Our location is in middle Tennessee.
Thanks for any help.

i ran across this bug during a night walk in Sabino Canyon, Tucson, AZ. It has a green glow in the tail.
It was in a riparian area but I found it on land crawling between two bodies of water.
I thought it might be s hellgrammite , but have not found a picture that is similar

Firefly Larva

Firefly Larva

Dear Lance,
This is not a Glowworm.  It is a Firefly Larva and they are in distictly different families.  We believe your individual is in the genus
Microphotus which is limited to western states.  Your individual looks very similar to this BugGuide image of Microphotus angustus, but that species is only reported in California.  Four other members of the genus are reported in Arizona, according to BugGuide, but no images of the larva are available.  Then again, it might be a member of a different genus.

Dear Bugman,
I would like to ask you if you know which family this insect belongs to.
It was found in Panama on the 20th of September (rain season) on the ground in secundair rainforest on 800m altitude (Rambala region).
I am very curious to hear what it could be.
With kind regards,

Beetle Larva:  Firefly or Net-Winged Beetle???

Beetle Larva: Firefly or Net-Winged Beetle???

Dear Stephanie,
This is a beetle larva, and it is either a Firefly Larva in the family Lampyridae or a Net Winged Beetle Larva in the family Lycidae.  The two families are very difficult to distiguish from one another when in the larval stage.

Dear Daniël,
Thank you very much!
Is thought it might be a trilobyte but they only occur in Asia if I am correct.
Cheers,
Stefanie

Dear Divya,
This is a Glowworm or Railroad Worm.  They really do glow in the dark.

Daniel, thank you so much! Wish I had known to test out the glowing, but it was really hard to google image a replica of long red black beach bug. Anyway, my 4.5 year old loved it:

Hi. So my mom and I recently discovered this insect in our house. He or She had the body of a centipede but only six legs. It seemed to be predominantly yellow with black bands of with red dots on them. We have never seen a bug like this and I’ve tried to find the name of it. When we found it, it was curling up so I didn’t get a high quality picture of it. It looks to me like a wireworm but none of the colors match up. Could you tell us what bug is this? Thank you
Signature: I’m not sure.

What a marvelous image of a Railroad Worm, an interesting common name for this Glowworm Larva.  Viewing the Railroad Worm in the dark will provide you with a wonderful light show.

This insect was found crawling on a red oak tree in our house yard., that we have been having trouble with what seemed to be Beatles boring into the tree trunk in the fall or late summer and then in the spring hatching out because we see sap running down tree. We live in Southwest Iowa and Harrison County Jefferson Township in the country.

Firefly

Firefly

Dear Cindy,
Your images are very blurry.  The first image we opened appeared to resemble a dead Firefly, but there are several similar looking species and we could not be certain due to the poor quality, however, your second attached image with the view of the underside clearly shows the light producing organ at the tip of the abdomen.  This Firefly is not boring into your tree. Fireflies are beneficial insects.  The larvae are predatory, and they feed on small creatures including on snails and slugs.  In an attempt to educate the public on the importance than insects play in the complex web of life, and because this Firefly that was found crawling and it appears it will crawl no more, we are tagging this posting as Unnecessary Carnage.
