PLANTHOPPERS (DELPHACIDAE)


Asiraca clavicornis - None.  I found this species at the meadows in April 2021.


Stenocranus major - One of 3 similar hoppers at the meadows on 27th March 2019 was retained and proved to be this species.  More were found in the same area of Reed Canary-grass on 2nd May and 16th September 2020 (and in 2021).

Stenocranus minutus - None.  I found this species at the meadows in 2018.


Eurysa lineata - One at the meadows on 20th June 2020 was my first record of this species.

Javesella pellucida - A total of 4 Javesella planthoppers found in my garden moth trap between 17th July and 1st August 2019 and 4 again between 31st July and 10th August 2020.  Also 3 at the meadows between 24th April and 8th May 2020.  Most were females, which I understand are not reliably identified to species level but there were single confirmed male pellucida here in each year and one at the meadows.  There was another male here in 2019, but it had been parasitised by a Stylops and although the genital capsule was present (and resembled this species) it was empty, i.e. no aedeagus etc.  I can only presume that these parts had either been eaten by the Stylops or else they had not developed properly as a result of the Stylops being there.

Struebingianella lugubrina - None.  I caught this species at home in 2018.

A good year for Bordered Beauties

Another White-bodied Conch Cochylis hybridella was probably the best moth on 20th August.  The species has only recently become established in the county and all four of my own records have been in the last couple of years.

An Ash-bud Moth Prays fraxinella was new for the year here.

This Bordered Beauty was my 7th here this year, a fantastic tally for a moth that I'd only ever seen that many times before, and only twice before in the garden.  It's a great-looking moth so a good year of them was very much appreciated.

The waxfly Coniopteryx tineiformis was new for the year for the garden, and only my second here.  I've had a few elsewhere though, and all these records aren't bad considering that until 2016 there was only one county record.  Other Neuroptera were the green and brown lacewings Chrysoperla carnea agg., 2 Cunctochrysa albolineata, Dichochrysa flavifrons, Hemerobius humulinus and 6 Hemerobius lutescens.

Among the caddisflies 3 Small Silver Sedges Lepidostoma hirtum were new for the year. The others were Ithytrichia lamellaris, 3 Hydropsyche pellucidula, 4 Hydropsyche siltalai and Mottled Sedge Glyphotaelius pellucidus.

The barkfly Elipsocus hyalinus was new for the garden.  There was also another Ectopsocus petersi.

The stunning leafhopper Zygina flammigera was also new for the garden, although I have suspected them in the past (they can be a bit tricky to identify positively).  Other leafhoppers included 5 Empoasca vitis, 2 female Kybos sp. and a female Edwardsiana sp. - in both cases males are needed for a full ID.  Other bugs were 2 Forest Bugs and 2 Tarnished Plant Bugs Lygus rugulipennis.

The following night was quieter - the moths were 2 Bird’s-nest Moths Tinea trinotella, Hawthorn Slender Parornix anglicella, Four-spotted Obscure Oegoconia quadripuncta, Little Mompha Mompha raschkiella, 2 Light Brown Apple-moths Epiphyas postvittana, 7 Common Marbles Celypha lacunana, Birch Marble Apotomis betuletana, 21 Common Grass-veneers Agriphila tristella, 7 Elbow-stripe Grass-veneers Agriphila geniculea, 2 Garden Pebbles Evergestis forficalis, Beautiful Plume Amblyptilia acanthadactyla, 2 Common Plumes Emmelina monodactyla, 2 Orange Swifts, 2 Blood-veins, Single-dotted Wave, Garden Carpet, 2 Double-striped Pugs, Scorched Carpet, 3 Brimstone Moths, Common Wave, 2 Light Emeralds, 2 Large Yellow Underwings, Lesser Broad-bordered Yellow Underwing, 2 Setaceous Hebrew Characters, 7 Six-striped Rustics, Square-spot Rustic, Lychnis, 25 Flounced Rustics, Frosted Orange, 3 Vine's Rustics, Spectacle and 4 Straw Dots.

There were no lacewings but Pond Olive Cloeon dipterum and Green Drake Ephemera danica represented the mayflies.  There was a good variety of caddisflies given the low overall numbers: Ithytrichia lamellaris, Hydropsyche pellucidula, Hydropsyche siltalai, Small Silver Sedge Lepidostoma hirtum, Mottled Sedge Glyphotaelius pellucidus, Limnephilus lunatus and Molanna angustata.

Among the beetles the water beetle Ilybius fuliginosus was new for the year here.  A Lesser Mealworm Beetle Alphitobius diaperinus was only the second I've identified.  There were also 8 Bradycellus verbasci and 2 Aphodius rufipes.  A Birch Shieldbug was the only bug.

The next day a wander round the meadows produced less than usual - 2 Chrysoperla carnea (green lacewings), Brown Rowan Argent Argyresthia semifusca, 3 Common Grass-veneers Agriphila tristella, a Common Froghopper Philaenus spumarius and a Red Fox.
