One of the great benefits of last winter’s cutting of large willows in the quarry is starting to be seen. The log pile that was created by the hard work of wonderful volunteers has come alive in this week’s warm sunshine, and is both a basking spot for Lizards and a prospecting site for the Wasp Beetle. This brightly coloured and attractive native longhorn beetle has been seen in good numbers all over the log stack, and hopefully making a new home for itself.

7-spot ladybirds are a regular sight everywhere around the Country Park, including the patch of nettles outside the VC. A close look at one revealed that it was unmoving and appeared to be sitting on a nest. The apparent nest is the cocoon of a parasitoid wasp Dinocampus coccinellae. The adult wasp is found in all continents except Antarctica and has been reported to parasitise 13 of the UK species of ladybird, but the majority are from the subfamily Coccinellinae, of which the species most frequently seen around the Country Park is the 7-spot ladybird. The adult wasp lays an egg within the body of the ladybird, that egg subsequently goes through three larval stages (instars) before emerging as a yellow maggot from the ladybird’s abdomen. It then spins a silken cocoon between the legs of the host, and pupates. The ladybird does not survive.

There is a new nationwide research project seeking to record the prevalence of Dinocampus coccinellae around the UK in order to determine whether it is increasing as a result of disruption to the natural balance between the 7-spot and the parasitoid wasp since the arrival of the Harlequin.

Information about this research project may be found here: https://ladybirdchallenge.co.uk/ and records of sightings are welcomed.

A group of us volunteers attended a meeting with management today thinking we were going to consolidate some points from our last meeting with regard to our working as an autonomous group. Little did we know that instead we were to be told that it had been decided that we could not operate in future without a Ranger present, despite having in reality done so for a number of years. The upshot being that with the reduction of staff it will only be possible to run 10 conservation days a year, this being in contrast to us having been doing  every Thursday and the first Sunday of every month plus some Fridays some 65+ days. This is a massive reduction and presumably the slack will have to be taken up by contractors and one can only wonder where the money is to come from when we are told that HBC has to make further cuts in spending in the coming year.

For us it will be so frustrating to see areas that we have been looking after deteriorate due lack of time if no-one else does do the work. It now remains for us to wait and see when these 10 days are going to be.

It seemed appropriate to mark the relenting of that persistent cold wind with a stroll in the quarry to see if any insects would appear in the very welcome sunshine. Winter clearance work by the Volunteers has created perfect new habitat on some of the banks in the quarry and enriched this site. A first glance at the unfurling leaves on willow regrowth near to the exposed rock faces saw a Cream-spot Ladybird and a brilliant metallic green/gold Weevil (Polydrusus pterygomalis). Turning into the open quarry a Small Copper butterfly was flitting around the Wood Sage and warming in the sunshine. A closer look at the Wood Sage saw a Green Tortoise Beetle and a Sloe Bug (or Hairy Shieldbug if you prefer). All of these beautiful insects were in habitat that has been created by the diligent work of the Volunteers, to whom we say thank you.

Early morning sunshine at the helipad found a beautiful grass snake basking in the longer grass at the Fairlight Road side of the site. Further inspection of the area found eleven 7-spot ladybirds, one of which was parasitised with a wasp (Dinocampus coccinellae). Nearby were two 16-spot ladybirds.

Further attempts to identify the plentiful small invertebrate wildlife of North’s Seat (and keep out of the bitterly cold wind) have found a Birch Shieldbug Elasmostethus interstinctus, a Cream-spot Ladybird Calvia quattuordecimguttata,  and another two Weevils – a female Polydrusus cervinus and a Polydrusus tereticollis.
