Holme Carr Great Wood, Rossington- Wednesday, 26 June 2024

Leaders: Ian Farmer & Tom Higginbottom

Holmes Carr Great Wood is a large woodland which borders the edge of Rossington and  what would have been the Rossington Main Colliery coal tip. There were many mature Pedunculate Oaks which were host to a number of galls. The most exciting galls were found in the more open parkland before we entered the wood. On the underside of an Oak-leaf we discovered 5 examples of the rare gall Cynips longiventris, the Striped Pea Gall.  A distinctive gall but one which is not frequently recorded.

In the wood we also found examples of Cynips divisa. Ian Farmer checked by pressing the galls, there is no doubt it was C. divisa the gall which is thick walled, whereas C. agama, similar looking gall is thin walled and collapses when pressed.

The wide-open pathways led to the discovery of galls on herbaceous plants.  The wasp Liposthenes glechomae causing galls on the buds of Ground Ivy.

After lunch we decided to investigate another nearby woodland, Hurst Plantation. We were fortunate to have the knowledgeable expert Jim Burnett to lead us through the woodland and ponds, remaining from sand and gravel extraction.

 The most significant discovery was an  old example of Andricus lucidus,  often referred to as the hedgehog gall,  a gall wasp rarely seen in the north.

Alder was common beside the ponds and host to the common mite galls Eriophyes inangulis  forming  pimples along the main vein of the leaf and E. laevis forming pimples all over the leaf. Slopes near the ponds were covered in  yellow Evening Primrose.

The most significant galls were discovered towards the end of our meeting. Jim had indicated that in 2022  a large part of the woodland had been burnt by an extensive fire. Many conifers and remaining Birch trees were silhouettes with  Bracken covering the understory.  But in the last part of the woodland not far from the car park,  Rosebay Willowherb was the dominant plant growing beneath the silhouettes of burnt trees. It has been often described as Fireweed. In our searches for galls Ian Farmer found the  leaf roll formed by the midge,  Dasineura kiefferiana and the even more unusual swelling of the stem formed by a moth, Mompha sturnipennella.
