LEAFHOPPERS (CICADELLIDAE) continued
SUBFAMILY TYPHLOCYBINAE (continued)
Fagocyba carri - One to light at the meadows on 7th August 2020 and one in the garden moth trap on 22nd September 2020. None in 2019 but I caught 3 here in 2018 (and one at the meadows). I also got round to identifying one from Wiveton Downs in 2016 which I had retained for checking (but didn't at that time know how). The RES key seems to imply that cruenta can be yellow or brownish-grey whereas carri is always yellow, but this is at odds with my experience. I don't think I've ever caught a cruenta that hasn't been yellow (some are strong deep yellow while others are washed out whitish yellow) but carri appears to be much more variable. The 4 carri I found in 2018 were all yellow appearing identical to cruenta but 2 of the 3 featured here (one from 2020 and the recently-identified one from 2016) were brown, and the other one from 2020 was intermediate. All of these brown or intermediate individuals had the pigment pretty much restricted to the top and centre of the wing, the costal region below being clear.
Fagocyba cruenta - 2 on my beach hedge on 21st June 2019 followed by a total of 9 in my moth trap up to 14th October. A total of 12 caught in my garden moth trap between 23rd June and 7th November 2020. Also recorded at Swanton Great Wood and Row Heath (West Runton) in late August 2019 and in Cornwall in October 2020. Quite a bit of variation in the intensity of yellow (males may average brighter but a lot of overlap):

Edwardsiana sp. - Another tricky genus where for the most part at least, females can't be identified. 8 females caught in my moth trap in 2019 and 3 in 2020, plus a few elsewhere. Also 2 males I couldn't resolve as their genitalia didn't quite match any of the species. One was probably a mal-formed rosae but the other was a complete mystery as I couldn't find its aedeagus. The following males were satisfactorily identified.
Edwardsiana crataegi - None. I've caught and identified this species here once, in 2018.
Edwardsiana flavescens - None. I've caught and identified this species here once, in 2017.
Edwardsiana geometrica - None. I've caught this relatively distinctive species here once, in 2016.
Edwardsiana lethierryi - A male caught in the garden moth trap on 29th August 2020. I've caught this species here once before and once at the meadows, both in 2018.

Edwardsiana prunicola - One on willow at the Cathedral Meadows on 21st June 2019 was the first I identified of this species.

Edwardsiana rosae - A male in my moth trap on 2nd July 2019 was the first time I've identified this species in my garden although it's the Edwardsiana I've identified most often elsewhere (including one at the meadows in 2018). 3 caught in Cornwall in early October 2020 - I'd caught 3 here in 2018 too.

Edwardsiana spinigera - A new species for me in 2020 but 4 males caught in the garden moth trap between 1st and 16th July.

Edwardsiana ulmiphagus - One in my garden moth trap on 14th June 2020 was a new leafhopper for me. It was followed by 3 in Cornwall on 6th-7th October. This species keys to Edwardsiana hippocastani using the RES key but if I understand other sources correctly this is now known as Edwardsiana ulmiphagus.

Alnetoidea alneti - Singles in my garden moth trap on 12th July and 16th August 2019. Athough I had seen this species before I had forgotten how similar they are to Fagocyba and Edwardsiana spp.

Arboridia ribauti - Singles in my garden moth trap on 14th August and 30th October 2020, my second and third records following one here in 2018.
