SUBFAMILY TYPHLOCYBINAE (continued)


Zygina angusta - One at the Cathedral Meadows on 29th March 2019 followed by one in my garden moth trap on 23rd August and another 3 between 24th November and 19th December.  Just one here in 2020, on 20th August.

LACEHOPPERS (CIXIIDAE)


Cixius nervosus - My first example of this species came to light at the meadows on 7th August 2020 and was then followed by one beaten from Oak there on 5th September.

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 rush of moths

Bank Holiday Monday was nice at the meadows with a number of new species for the site recorded.  I counted at least 13 Large Red Damselflies and butterflies included 8 Orange-tips, 4 Brimstones, 2 Holly Blues, 2 Small Tortoiseshells and 3 Speckled Woods. Moths weren't especially well represented with just Common Nettle-tap Anthophila fabriciana and another Vetch Piercer Grapholita jungiella.  There were Dark-edged Bee-flies and bees included Buff-tailed Bumblebee.

I haven't been using my new sweep net very much as it provides so much material I end up spending all my hours working through it all in my study and not having enough time to go outside - it's bad enough anyway!  This was exemplified today when a single sweep through some grass and Ground Ivy produced the bug Stenodema laevigata, the planthopper Javesella pellucida, a rove beetle Tachyporus sp. (probably Tachyporus hypnorum), a Pea-leaf Weevil Sitona lineatus and a spider Metellina mengei, the first time I've identified this species.

Among the flora, Greater Celandine was a new species for me.

That evening a White-shouldered House Moth Endrosis sarcitrella was new for the year (appearing in my study) while the moth trap delivered two more additions to the garden year list, Pebble Prominent and Flame Shoulder.

The following night was remarkably good compared to recent nights, or indeed any night this year so far.  Surprisingly a couple of other moth-trappers I've spoken to didn't have the same experience but for me it was massive!  Ok, 45 moths of 25 species may not sound like an extroadinary catch, but no less than 14 of these were new for the year.  Bear in mind that I trap every night, new moths for the year tend to be fairly well spread out.  The best night for new additions so far this year was 21st April with 6, and these 14 increased my year-list by over 20% in one foul swoop.  More nights like this please!

The 14 additions to the garden year list were: Little Ermel Swammerdamia pyrella, Pearl Dwarf Elachista apicipunctella, 3 Little Dwarfs Elachista canapennella, Chinese Character, Garden Carpet, Grey Pine Carpet, 2 Common Pugs, Brimstone Moth, White-pinion Spotted, Coxcomb Prominent, 2 Orange Footmen, Cinnabar, Least Black Arches and 2 Shuttle-shaped Darts.

The other moths caught that night were 2 Beech Midgets Phyllonorycter maestingella, Common Flat-body Agonopterix heracliana, Light Brown Apple Moth Epiphyas postvittana, Bee Moth Aphomia sociella, Red Twin-spot Carpet, 4 Brindled Pugs, 4 Waved Umbers, another 4 Chocolate-tips, 4 Muslin Moths, Hebrew Character and 3 Nut-tree Tussocks.

It was good for other insects too.  My first Mayfly of the year was a Large Dark Olive Baetis rhodani, actually a new species altogether for me, although I think some of my earlier attempts to identify mayflies were flawed so it may be that I've misidentified them in the past (I made a significant breakthrough with mayflies half way through last year when I realised how easy they were to sex).

Three species of caddisfly tripled my caddis year-list: Mottled Sedge Glyphotaelius pellucidus, Limnephilus affinis and 3 Limnephilus auricula.

Beetles included Great Diving Beetle Dytiscus marginalis, Black Sexton Beetle and my first Cantharis cryptica (one of the soldier-beetles) of the year.  Check out the suction pads on the underside of one of the Diving Beetles tarsal segments...
