Unusual pupae looking things in the attic

[yorkney]

Hello, I hope I am in the right section. I thought I would create some storage space in the attic, so I started to level out the insulation. I found these in the middle of a section of insulation:

I look forward to any ideas, thanks for reading.

Regards

put something in to show the scale.

And one in close-up, next to a 50p piece.

I may be quite wrong here, but they look more like droppings!

 

[yorkney]

Thanks for the responses, I'll take some close ups JohnD. JBR, I don't think they're droppings, they're very light weight due to being hollow, looks like something has crawled out of each one.

 

[JBR]

Interestinger and interestinger. Have you seen anything flying around up there or, worse, crawling around?

 

[yorkney]

JBR, nothing flying around. I'll get some pics up , I am desperate to find out what created those. Just hope it isn't anything sinister.

Have you seen the original Alien film? they look like the eggs

 

[yorkney]

Nige F, same shape but a lot smaller

 

[freddiemercurystwin]

So small aliens then?

 

[MysticalGandy]

Its not Bat poo then?

 

[noseall]

They look similar to sand bee pupa husks.

 

[yorkney]

Must be small aliens, not bat poo and thanks for the sand bee suggestion. I will post pics which will give an idea of the size of these "alien" pods.

thanks again

 

[yorkney]

The waiting is over, hope the pics do not disappoint. Thanks for looking.

they do look like droppings to me, I've seen similar in garden pots, I assumed they were squirrels.

if you cut them open, are they solid, hollow or containing dead larvae?

 

[yorkney]

They're all hollow with a hole, something has crawled out of each one.
