I would really appreciate some help identifying these larvae which I have found under my floorboards. They were discovered while clearing up rubble under my floorboards. They are about 2cm long, dark brown/green-ish colour, and have a red-ish head. Thanks in advance for any help you can offer.
They look very much like Crane fly larva and are commonly kown as Leatherjackets. The Crane fly is a Daddy longlegs.
They have legs and an easily visible head capsule so they're not leatherjackets. I think they have false legs (behind the true legs) so would guess they're moth larvae, but I'm far from sure. How would the adults get under your floorboards?
I have no idea how they got under there. The floorboards are underneath laminate flooring, and there's no obvious way through. Perhaps through one of the air bricks? We do get moths in the house occasionally and I think they are clothes moths, but these do not look like the clothes moth larva I have seen online. The larvae were buried into the rubble and sand under the house. If we hadn't been disturnbing them I don't think they would have stared being so active. Thanks for your help with this - it is appreciated!
I don't think I can be of much help. The larvae may only be in the rubble to pupate - it's hard to see how they could obtain much nourishment there. So, I wonder if they crawled in there from outside. The only other suggestion I have is that they may be parasites or scavengers in a wasp nest - do you think there might be one there? But frankly I'm clutching at straws. Let's hope someone comes along with an answer.
