This is the striped Nymph form of this species an eartly stage 1 Nymph still not showing developing wing books . When Adult it looks like below . The Nymph is aprox 3 - 4 mm and the adult Length 4-5 mm. It is prolifically abundant on hedgerow vegetation this time of year especially Nettles It can be very variable in colour form and tends to be darker with more intense marking on the Cuneus Post Spring Hibernation less vivid specimens are seen through out the year
Head width Aprox 1/2 Pronotum width,
Length of second antennal segment GREATER than head width.
A site meeting was held led and attended By Hugh Firman ( Conservation Officer ) and Robin Dalton ( Countryside Officer) . I am sure ALL concerned thank them both for giving up their restricted time at the end of a working day and for an effective and courteous lead . It was also attended by CBWG and FEET (Freshwater Environment Ecology Trust) and others interested in the protection of the reserve It principally dealt with future Site work in each of the key ecological zones on Tag Loop and Brookfoot Loops .( NOT North Loop which as yet currently is not on the Authorities Schedule as a LNR )

FEET - As always we will work responsibly
with the Authority to provide solutions and indeed as part of our own remit
work closely with farmers when advising on Environmental Stewardships and enhancing
Wildlife Biodiversity arrangements which often reciprocate . If that is a
limiting factor and I really don’t think it is , ie depth of Cut , One Cut
between mean generational periods (Lepidoptera) Then (i) All
Stakeholder Groups (FEET included) must work harder to gain resource input (2) The Authority must adequately fund Countryside services to be
able to do that work
Post and pre Season monitoring is
essential in deriving local best Practice interventions .
This years Burnet Moth counts are unpredicably nationally down , and this correlates with a reduction of in number of Birds Foot Trefoil areas at the junction of Tag Loop Meadows a small a qualitive survey one of a number of potential factors. Birds Foot trefoil is the Yellow Plant that is the larvale food plant for Narroe 5 and 6- Spotted Burnets MothColonies that normally are abundant on the reserve in July
anticipated question , “ how do we know that it is not ..” we know national
Burnet Numbers , We have chronological Met Data , what we don’t have is the
Intervention monitoring , ie who did what & when.
FEET Position This years post meadow cut fauna reflects a possible strategy change in a number of respects Boosting Discrete stands of Bird Foot trefoil. Alterring the depth of the cut to allow a lepidoptera to survive or over winter as larvae in root systems and obtaining this years single cut toward the end of July between mean generational periods . Undertaking of Moth Survey recording prior to cutting
Re North Loop – Floristic Planning – FEET generally hold
seed for projects like this . Large quantities of seed will be needed post Nov 2014 for floristic
zoning on North Loop – in the interests of outcome seeding should be though through in
terms of local soil aspect , hill slope hydrology and placement in so far as what
might constitute a suitable micro habitat., mosaic or niche FEET will assist Authority on general advise to make this a succesful intervention
Desire Lines and Public access . The intention to circum-navigate the Lagoon or to abridge Areas between Canal / River
by multiple bund like access points needs to be addressed in order to provide quiet breeding areas impacted less by human contact for Waterfowl and other Birds
FEET Position solution is a
simple one a small guide fence line abridging the front of lagoon and along the
edge of the Willow Car as pointed out vegetation will grow back and
naturally limit access and also protect any one from visual impairment straying into water of down inacessible slopes . Tree Removal in the Carr. We would advocate leaving the Willow alone as most of the important ecology in the Carr is generated through leaf litter (Fungi and Specific Plants ) This Carr has had the alleged top soil 300 mm by the CEGB removed
probably when the local authority skimmed off the best of the fly ash for building
the by pass . The ground is the naturally uneven and the Carr
adopts and holds good moisture layers and humidity levels within and across
seasonal rainfalls factors that are important to entomology fungi and other classesof flora and fauna . Its our view that the action of direct sunlight on the fly ash will simply negate the positive effect of leaf litter or the important role of damp woodland provided by the Shrub and Tree layers
3. Lagoon . Lagoon management has been good with a great deal of hard work by many individuals
FEET Position FEET acknowledge the enthusiasm and dedication to
have Lagoon filled by the alternate Group. In principle we would like
nothing more than to see A body of freshwater created Freshwater is the life
blood of all natural diversity but In Practice the Geology /
hydrology/ & Intervention on the site make this an expensive and difficult
project and with the nature of proximal water table and absence of underlying
Geophysics or Ground study a project which could potentially not meet the
objective of water retention. Additionally, adding a Volume of water in a Flood
Plain control Area is an implication that might preclude this project. If
it can be done and someone is willing to pay to do it that would be fantastic
4. Tag Cut Pond Scrape Again the emphasis is on
Intervention monitoring . The Solution of a Ram Pump or natural Hillslope
gradient to top up the depleted pond scrape in principle is a good
solution in our opinion we would make no assumption without measuring and monitorring would not assume creating a dammed area at that
proximity to mine run off (including significant iron contect etc) would
promote the freshwater ecology indeed it may have the opposite effect with
Westerly Proximities of the Tag with good flow rate having better water quality
measures than the Easterly section currently being developed . The adjacent
Hillspope is sufficient to provide a Hydrostaic Flow or supply to the Scrape
without necessarily damming it . As stated at the Site meeting it will not
introduce new Species of Dragonfly which have not been traditionally found and depend on specific Water Parameters (DO, Temp , and other factors) With Larvae of many species Eg Hoverfly taking
in some cases up to 3 years to complete cycles the effect of interventions can
be delayed emphasis is on Intervention monitoring .FEET Position Assist in monitorring water quality and intervention impact but not at cost to the Trust
Mammal Survey As a Stakeholder Group it would have been nice have been briefed on the
Objective, Methodology , Skill Base and purpoise of this work , which incidentally
only became apparent when conveyed by a local dog walker who's dog had picked
one up !! FEET have recently appointed a port folio for Mammal Welfare Member , and Environmental Law Port folio
Benches Feedback -
FEET Position We would much prefer the Use of large Stone such as is found near the Tree Sparrow Area and Bird feeding area . (i) It is not man made and less visually intrusion (ii) It is permanentand not open to destruction or theft (iii) Ameniable to cleaning etc Re Newt Corner there is no major need to extend by any significant amount hard surfacing of the pathway to the proximity of the lagoon edge
In General The Calderdale Reserve continues to throw up New and Interesting Records for Yorkshire . and is a reflection of the hard work interest that many have given to the reserve.
It is a grassland species associated with Gramineae. It differs from other Capsid bug in its feeding habit , and feeds lower down on the stems, as opposed to the flower spikes and developing grains which is the usual feeding area
Key Identification Factors
A Black Capsid Bug oval in form with black forewings
The 2nd antennal segment is swollen at its distal end The widest extent of the 2 nd Anttennal segment is more than twice as broad as its narrowest point
Adult head and pronotum may vary in colour from rusty brown to black ish
Short to medium hairy plant. Leaves with 4 to 10 pairs of oblong leaflets. Flowers, whitish with a pale lilac tinge, small 2 to 4 mm with 1 to 8 in a short raceme. Pod black, 6 to 11 mm 2 seeded and hairy, usually black.
Smooth Tare is similar, but the two species can be separated with care. Smooth Tare flowers are larger and more purple in colour. See the marked diagram below for a comparison of the two species.
Dry grassy places, rough grassland, roadside verges. At the grassy area at the entrance to reserve from Anglers Car Park and throughout
Description Polymerus species are medium-sized bugs which are predominantly black or black and yellow in colour. The upper surface is covered in scale-like golden or silver hairs and the tibiae bear strong black spines.
In P. unifasciatus the pronotum, scutellum and corium are entirely dark and there are orange markings on the cuneus. The tibiae have broad pale bands.
Fairly common on bedstraws (Galium sp) in a variety of habitats across much of the UK.
Description Ground colour varies from pale olive-green to almost black, the head and front of the pronotum are usually dark, as are the 1st and 2nd antennal segments. The dark margins of the hind femora are a very useful identification feature; these are present in late instar nymphs also. The spines on the hind tibiae are equal to or longer than the tibial width and generally arise from black spots. The pronotum and forewings are covered in dark hairs.
Malthinus seriepunctatus is one of the smallest of the Cantharidae group, measuring around 4-5mm in length. There are about 40 species of Soldier Beetles UK and most are frequent visitors to thistles and umbelliferous flowers.
Description A rather attractive species which does not tend to vary as much as its congeners. Frequenting woodland habitats, it flies in July and August, and is locally distributed in the southern half of Britain, but absent further north.
The larval foodplants are a range of woodland grasses, including wood millet (Milium effusum) and wood-rushes (Luzula spp.).
Tufted grass to 100 cm, softly greyish hairy throughout, the inflorescence often with a purplish pink tinge, especially when young.
Similar to Holcus mollis but that species has more or less hairless stems whereas Holcus lanatus has downy stems. The node hairs of Holcus lanatus are not as long as those of Holcus mollis. The two species do hybridise to give Holcus x hybridus.
In all types of grassland, roadside verges and waste ground.
This is the Birch SB - It has a white discoid parasitic fly egg attached whixh is likely the Tachnid Phasia hemiptera a known parasite of shieldbugs. Shoulders are rounded and less angular than the closely related Hawthorn SB
Aphrodes species generally have a sharply pointed vertex which always has a median keel. They can be very variable with distinct forms occuring in different habitats. Females in particular are often difficult to identify.
The host plants are a range of common species, including dandelions, thistles and nettles, and it occurs widely across the UK, but particularly in the south.
