Boring insects in log pile

Recommended Posts

Hi, anyone know what these insects are and should I do something about it. The logs are ash and were felled and processed last November stacked up in my sunny carport. 

I think they are only going through the bark. They look similar to ants. Flying Wood ants ? No sign of beetles. Don’t fancy taking them in the house. Lots of sawdust too. 

Any ideas anyone. Many thanks.

I've no idea what the flies are but the 5th picture looks like an ichneuman wasp and it is presumably parasitising the beetle eggs that are hatching and boring the holes and frass in your later pictures.

The one with the pointy tail looks like a wood wasp, they are probably male and female of the same thing. American article here on them

I think that both of those are parasites on the wood boring beatles in your logs. The second picture has a very long ovipositor which makes me rhink it is some forms of of parasitic wasp.

So the wasps are feeding on the ash bark beetles and their eggs. And the ash bark beetles are feeding on the bark and are not likely to cause any other damage beyond the bark of the ash logs. 

Thats all good news.

Thanks all for your help on this.
