Blackberry Leaf Midge
The larvae of the Blackberry Leaf Midge (Dasineura plicatrix) cause galls to form on Bramble.
The young leaf is creased, pleated or buckled with thickened veins.
The larvae are present in the creases briefly in late spring and early summer.

The following images show various Chequered Hoverflies (Melanostoma scalare) that were seen hanging from the grass False Brome (Brachypodium sylvaticum ) at a height of about a metre from the ground.
Also of two attached to Common Agrimony (Agrimonia eupatoria)
They had all been infected by an Entomophthoragic fungus
♂︎
Early stage of infection presumably.
Well and truly stuck and not moving.
The hoverfly looks pristine and wings have yet to open
On Agrimony (Agrimonia eupatoria)
♀︎
Early stage the hoverfly looks pristine and wings have yet to open. No movement.
The lower hoverfly actually flew off the one attached to the grass but presumably had been infected.
Very different stage.
The wings are open and you can see the spores beginning to cover the insect.
A much more advanced state. The hovers are well and truly adhered to the plant. The insects have reached about a metre from the ground.
The wings are outstretched and the spores are pouring from their bodies.

"The Zombies"
Entomophora fungal species
elicit dramatic behaviours in infected hosts
to
promote optimal spore dispersion
The genus Entomophthora:bringing the insect destroyers into the twenty-first century.
The images above show examples of infected hosts that have climbed the plants ('summiting disease') to give the fungus the best chance of spore dispersal.
When the proboscis touches the plant it adheres and thus effectively glues the hoverfly in place.
The wings will eventually raise up away from the dorsal abdomen
The legs have grasped the plant as well.

Largely females but at least one male was found.
