Original Hedgerow, leg 1.

 

Frequent heavy showers.

I've been staying away from this location since the hedge and verge were severely cut back in June. It has now recovered sufficiently to show traces of wildlife.

Firstly, a Sawfly leaf miner on Coltsfoot: Acidia cognata. The grazing marks (and the larva) can clearly be seen in the under shot. The dark dots are dung (or "frass".)

    

A Harvestman, also on a Coltsfoot leaf.

This fungal rust on Coltsfoot is Puccinia poarum. Fungal rusts often have alternate hosts. In this case, the alternate is Poa sp. - a family of grasses. I often wondered why rusts can have alternate hosts until I realised that the leaves of e.g. Coltsfoot are only present for part of a year, and the fungus needs another host for the period when the leaves are not available.

    

I think that the seed 'clocks' of composite flowers are quite distinctive. It would be interesting to see if the plants can be identified from clocks only. Groundsel on the left and Spiny Sow-Thistle on the right.

    

 

These galls contain the larvae of a parasitic fly - Jaapiella veronicae. The host is Germander Speedwell.

 

Sori of Male Fern are showing on the few plants that weren't cut back earlier in the year. As I showed recently, the cut-back specimens are sterile.
