Ometeo Posted March 19, 2010 Report Posted March 19, 2010 Hello, I found these in Socal and am trying to get an ID on them... larvae found on fallen, rotten wood. Thought this guy was a Scaphinotus sp. want to make sure. Bembidion sp? Thanks in advance, Ometeo Quote
ando Posted March 20, 2010 Report Posted March 20, 2010 The last one is some species of Chlaenius. Quote
Mashku Posted March 21, 2010 Report Posted March 21, 2010 Hi, the Larvae is a Elateridae sp. maybe... Greetings, Mashku. Quote
Dynastes Posted March 23, 2010 Report Posted March 23, 2010 I wish I knew what the larva was but it looks nothing like the different elaterid larval forms I know of. Maybe an iron clad? Quote
ando Posted March 23, 2010 Report Posted March 23, 2010 Can you raise the larvae into an imago? Quote

Ometeo Posted March 23, 2010 Author Report Posted March 23, 2010 Thank you all. Orin, I am now a bit confused. I have found more click beetles than iron clads in the area, but have actually found adult Elaterids in the immediate vicinity where the larvae was found. It is still in larval stage and is eating hungrily through the wood, I'll have to wait for it to hatch. Ando, thank you so much, I am now looking at the different species of Chlaenius in the area. Thank you too Mashku. Lastly, how can I differentiate between Scaphinotus sp and Calosoma sp.? I am a bit stumped on the middle picture. thank you all, Ometeo Quote

I think, and the kaeferforum Guys too, the larva is new eclose, i mean it left it old skin... maybe. Quote
Mashku Posted March 23, 2010 Report Posted March 23, 2010 Maybe an iron clad? What is a iron clad ? You dont mean the Ships ? Quote

Ometeo Posted March 23, 2010 Author Report Posted March 23, 2010 You have try it here ? Greetings, Mashku. Hey Mashku, the iron clad beetles are Phloedes diabolicum. don't understand the question there... Ometeo Quote
Mashku Posted March 24, 2010 Report Posted March 24, 2010 I´m lost the Link, sorry : http://bugguide.net/node/view/15740 Quote
Ometeo Posted March 24, 2010 Author Report Posted March 24, 2010 I´m lost the Link, sorry : http://bugguide.net/node/view/15740 ahh... bugguide. Yup, thanks Here's some more pics of the first larvae, I did notice two pronounced "horn" like structures in the last segment of it. (see picture #2) Also, there are some markings which can be clearly seen on the dorsal side (see pictures #3 & #4) I hope this aids in the identification of it. Quote
Ometeo Posted April 6, 2010 Author Report Posted April 6, 2010 Turns out the little larvae that remains unidentified was not alone... I've just spent ~1 hr looking at the log where it was originally found and it turns out it is chock-full of them. Also noticed that the little larvae is indeed little... must be an L1... I extracted 4 others of various sizes (and left three more alone in their little tunnels), one of them, the largest one, is at least three times the girth of the small larvae, and at least 1 1/2 times the length. I will have to take pics tomorrow and start a new thread, but with a later instar, identification *may* be easier... Quote
Ometeo Posted June 11, 2010 Author Report Posted June 11, 2010 larvae pictured is pupating. Looks like it might be Elateridae afterall. Quote
Peter Clausen Posted June 12, 2010 Report Posted June 12, 2010 Interesting posts! In my experience the Calosoma are significantly larger than the Scaphinotus, at least the few species I've encountered in the wild and the online hobby. The Ironclad beetle family can be found at the following link: http://bugguide.net/node/view/5779/bgpage but this is the most familiar species, I think... http://bugguide.net/node/view/54852/bgpage Many people confuse ironclad beetles with the similar darkling beetles, but they are in a different family.

Ometeo Posted June 14, 2010 Author Report Posted June 14, 2010 will try, it is pupating against the plastic in a container, although the plastic is clear there also seems to be a bit of debris that might show up in the pic. Quote
Ometeo Posted June 30, 2010 Author Report Posted June 30, 2010 I was wrong again, but Orin was right turned out to be Phloeodes diabolicus, nice little sucker at that. The other larvae are an Eleodes sp., not sure which, I've taken several pictures of their development and will post them as soon as I can. Quote
