Last time I contacted you wonderful folks I sent you pics of what you later identified as a scarab beetle grub, or June bug grub. I have also found another creature, very similar, yet different to that other grub. The ”head” of creature number 2 is a different color and it’s ”arms” seem different. Also, crazy creature number 2 is FAST. I have video of this thing wiggling across the floor on it’s back, legs up in the air! so odd… can you identify what this one is, too? Thanks!!!

Crawlyback

Hi Bef,
This is also the grub of a Scarab Beetle, but the behavior you describe indicates it is most likely a Crawlyback, the larva of a green scarab known as a FigeaterCrawlybacks are often found in compost piles.

Hello!
Found this creature in my garden. What is it?! Guessing it is some kind of moth larvae but I figured you were the best resource to find out for sure! Any info is greatly appreciated.

Dear Bef do Def,
This is the grub of a Scarab Beetle, most likely that of a May Beetle, commonly called a June Bug.

Flathead Borer Larva

This is a Flathead Borer, the larva of a wood boring beetle in the family Buprestidae.  Adults are often brightly colored with metallic elytra, and they are called Metallic Borer Beetles or Jewel Beetles. It is impossible for us to determine the exact species.  You do not need to worry about this larva feeding on your furniture, though there are reports of adult beetles emerging from milled wood and furniture as many as fifty years after the wood was harvested.  You can see more images of Flathead Borers on BugGuide.

Subject: Big Ol’ Larva – Carpenterworm?

We were splitting wood this weekend, and found this large larva inside one of the interior live oak rounds. We believe it to be a carpenterworm larva – can you confirm? As you can imagine, it was not happy to have been revealed to the world, so our size comparison with the measuring tape isn’t quite in alignment.
Love your website!
Thanks so much

Prionid Grub

Hi Megan,
This is the grub of one of the Longhorned Borer Beetles, most likely a Prionid, and possibly the California Prionus.  See this image from BugGuide for comparison.
  According to BugGuide:  “Larva feed primarily on living deciduous trees (oaks, madrone, cottonwood) and are also recorded from roots of vines, grasses, and decomposing hardwoods and conifers. Will also attack fruit trees growing on light, well-drained soils (e.g. apple, cherry, peach)”

I found this bug back in September 2010 in Maryland. He was very interesting looking. It did not like me very much, especially when I picked it up. He was large, almost 2 inches long. Not squishy like a maggot. Thanks so much.

Scarab Beetle Grub

Dear Curious and Curiouser,
This insect larva is more than just “grub-like”.  It really is a Grub, the acceptable name for the larva of a Scarab Beetle, though other beetle larvae and insect larvae are also called Grubs.  You did not indicate exactly where it was found.  Many large Scarab Beetle Grubs are found in rotting wood since that is their food source.  Other Scarab Grubs, notably those of June Beetles, are frequently found while digging because they feed on roots.  Other Scarab Grubs are commonly found in compost piles.  We will be postdating your identification request to go live later in the week since we will be away from the office for a short time and we like having new posts on our site on a daily basis.

I just sent a picture of a grub we found in a dead slash pine in Florida. After checking a little further, it appears to be the larvae of the flatheaded or metallic wood borer. We also found a few of them in the tree. Here is the photo again for reference. Keep up the great work!

Flathead Borer

Hi Poolman,
What a beautiful Flathead Borer and we are thrilled that you managed to identify it in our convoluted archive with its nearly 15,000 postings. We expect that David Gracer would report that it is an Edible species and most likely a tasty morsel.

Caterpillar ?Cicada larvae
Location: Michigan

I found this caterpillar in the garden on a sunny day in May in Michigan. It was very fast and before I got my camera it disapeared. When I located it, it had burrowed head first into the leaf litter on top of the soil. It had some bristles near the head. Looks like a cicada larva to me but the pictures I saw looked different.

Scarab Beetle Larva

Hi Linda,
This is the larva of a Scarab Beetle and it is commonly called a Grub.  Though we are uncertain of the exact species, we suspect it might be the larva of a Green June Beetle,
Cotinis nitida, which you can find pictured on BugGuide.

Thank you for the identification. It certainly does look like the one in BugGuide. I forgot to mention the size, it was large, at least 3 inches. My bug book shows the Green June Beetle larvae at 2 inches. I love your site and have it bookmarked. Thanks again, Linda
