HERTFORDSHIRE SITE RECORDS.

A Report of Arachnida (Spiders and Harvestmen) found on the reserve up to May 2005 + Additions following 15/09/2013 BioBlitz and 13/07/2014 Minibeasts BioBlitz + later dates to 2018.

Over the last few years the author has made a significant number of visits to the reserve to investigate the arachnid fauna of the site, and this culminated in 2004 when permission was granted for a limited amount of pitfall trapping to be carried out. The survey was an endeavour to generate records for the site, for Hertfordshire and eventually for the records to be submitted to the national organiser of the Spider Recording Scheme of Gt. Britain.

The main method of collecting specimens in the past has been sweeping the vegetation and beating the foliage and this has produced many records and will be continued in the future. However there are many spider species whose habitat is on the ground and pitfall trapping is a convenient method for finding these spiders many of which are only 1-2 mm in length.

The traps, which are plastic cups of the coffee dispenser variety, are inserted into the ground, in this survey 3 cups per site at approx 1 metre apart, and contain a solution of 25% Ethylene Glycol (Anti-Freeze) in water with a dash of Teepol (Washing up liquid) to reduce surface tension. These are left for periods of a week or more, then the contents are sieved out for identification and the cups replenished. In this survey the traps were installed at the end of March 2004 and serviced every week or two until they were lifted and trapping ceased on 09/11/2004.

Three sites were chosen in places where there would be little or no disturbance to the bird life of the reserve. Site A was in woodland to the left of the main path fairly close to the perimeter fence. Site B was at the western extremity of the reserve in undergrowth near to the brook and Site C was in the wild flower meadow.

A total of 37 species were identified over the trapping period and are listed in Tablet. This is a somewhat disappointing result, I would have expected more species, but my traps seemed to lose their efficiency after some weeks of use and needed replacing but suitable replacement cups could not be found the design having changed.

The complete list of species identified over the last 12 years is shown below and on Table 1 and the reserve list totals 64 species of spiders and 5 species of harvestmen. All these are reasonably common spiders, only Philodromus albidus is a Nationally notable B species and this designation may not now be justified as it turns up in lots of places in Herts. There are undoubtedly many more species to be discovered on the reserve including some very common ones, and significant areas of the reserve, particularly beyond the Shell hide, remain to be investigated. I would expect a list in excess of 100 species to be the final result and I hope to be able to continue to my search to add to the knowledge of the invertebrate fauna of the reserve.

My sincere thanks to the committee for allowing me to sample the arachnids of Maple Lodge.

Maple Lodge Nature Reserve BioBlitz 2013, Araneae — Spiders

The identification of the specimens collected on the 15^th September has now been completed. Only 14 different species were identified, five of which were new to the previous list from the reserve. A large number of the specimens were immature spiderlings which were unidentifiable to species and were discarded. Fourteen species for a whole days collecting is very low but given that the previous days were predominately wet and the vegetation on the day was still very wet and so collecting methods restricted to mainly observation together with a limited amount of sweeping and beating, the low species total is understandable. The spiders collected were mainly the most common species. The most notable capture was Nuctenea umbratica, a spider with a large orb web. This species is largely nocturnal and with a flattened body secretes itself in cracks and under bark during the day. Although fairly common, its niche habitat makes its collection a pleasant surprise.

With these five new discoveries a total of 69 species has now been identified on the reserve since I started recording in 1993. Undoubtedly there are many more species, some very common, awaiting discovery on another day, but I would recommend that other collecting strategies will need to be utilised, i.e. extensive grubbing of the ground layer on hands and knees together with beating the tree vegetation and also more pitfall trapping. To do this you will need more trained volunteers and ideally arachnologists , a very scarce resource in Hertfordshire.
