In July we came across this flower when walking in the bog. Is it a bog orchid?

It’s the club-horned sawfly with metallic green-gold stripes. It lays its eggs on devil’s bit scabious so the larvae can feed.

I found these slimy creatures in my comfrey brew. They were about 2cm long with a 3-4cm threadlike tail. Are they harmless or an invasive species? 
Michael Ruddy, Castlebar, Co Mayo 
These are the rat-tailed maggots, larvae of the drone fly, a hoverfly that lays its eggs in stagnant water. The tail is used as a periscope to breathe.

In mid-July a flock of black-headed gulls were twisting, turning, rising and diving over the local gardens catching insects. What could be of interest to such large birds?  
Brian Collins, Raheny, Co Dublin 
They were feeding on the mating flight of ants. The young queens and males emerge from their nests in amazing local co-ordination, when the weather conditions are right. The mated queens return to found new colonies; the others die.
