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

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.

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.

Possibly Firefly Larva

Possibly Firefly Larva

Dear Werner,
This is some species of beetle larva, probably either a Firefly or a Netwing Beetle.  It is very difficult to distinguish the family from the very similar looking larvae.   There is a similar looking image posted to iSpot.

Daniel thank you so much for the mail.
You made my day and my whole family’s!
We’ve been sending the video on all day.
The most amazing part is i own a company called Firefly in South Africa!
I love finding new bugs to identify but never came across one of them before.
I will research their life cycles tonight.
Thanks again and we will happily donate to your site.

Hi! I caught this firefly stretching its abdomen and folding the edges of its wings last night (July 1, 2015), in SW Virginia, about an hour & a half before dark.
There’s a video here: https://www.youtube.com/watch?v=8GAPXxUQ2nI
What’s it doing?
Also, have you ever noticed, if you have a firefly on your hand, it always wants to climb to the highest point to take off? You can turn your hand over and it will turn around and head for the new high point. Sometimes you can do this many times before it flies away.
thanks!

Dear Firefly paparazzi,
Our guess is that this Firefly is preparing for its maiden flight, that it just emerged from the pupa and it is trying out all its parts before taking off in search of a mate.

The night of June 27 , 2015 22:15 I was returning from a very long hike in the front range of Colorado Springs. As I walked up the the HighiDrive road I noticed what looked like the reflection of the moon light off of a crystal in the granite of a large rock. As I moved the light didn’t go away. Upon closer inspection it was very green in color. I knew it must be chemoluminesance. I grew up in these mountains for over 40 years. I have never seen this here before. It was at 7520ft and there were several of them along 1/2 mile portion of the road. The one in the photo was much brighter then the other ones I saw. The question is what is the life cycle of this insect and what are the limiting factors keeping there numbers down? Photo attached. Thank you.

Glowworm

Glowworm

Dear Bob,
Though they are commonly called Pink Glowworms, this member of the genus
Microphotus is actually a Firefly in the family Lampyridae, and not a true Glowworm in the family Phengodidae.  There is not much information on BugGuide.  In a 2005 posting on our site, we learned through Eric Eaton who contacted an expert that:  “He notes that they were all females collected in June and July and that, although their identities are not certain, they are probably pecosensis. “  Based on information we have learned through the years, we suspect this is an adult, larviform female.  We have been receiving numerous recent comments to our Pink Glowworm posts regarding new sightings.

Dear Liz,
This is a male Glowworm Beetle, probably
Phengodes plumosa, and it is perfectly harmless.
