Review of 2019 and 2020 - Bugs: Plant bugs - part 7: Phylini II (Phoenicocoris to Psallus)

PLANT BUGS (MIRIDAE) (continued)


Tribe PHYLINI (continued)


Phoenicocoris obscurellus - One in my garden moth trap on 13th July 2019, my second record here following one in 2018.

Phylus coryli - One in the garden on 25th June 2020 came to a pheremone lure trap for Yellow-legged Clearwing.  I caught 5 in my moth trap in 2017-18 but none recorded in 2019.

Phylus melanocephalus - I gather that 'Phylus palliceps' is now considered to be a variety of Phylus melanocephalus and not a separate species - both forms occur here though the orange-headed palliceps type are commoner than the original black-headed melanocephalus.  Singles caught in my garden moth trap on 24th June and 16th July 2019 (both palliceps-type) and 7 between 11th June and 4th July 2020 (3 palliceps-type and 4 traditional melanocephalus).  Also a black-headed one swept off Broom at the meadows on the earlier date of 1st June 2020.

Plagiognathus arbustorum - One in my moth trap on 24th June 2019 was new for my garden; another here (found indoors) on 6th July 2020.  The same day as the latter one on St John's Wort at the meadows and then one there on Hogweed on 20th July.

Plagiognathus chrysanthemi - One swept at the meadows on 20th July 2020, my second record of this species.  Then a week later one in the garden moth trap, my first here.

Psallus falleni - 4 males in the garden moth trap between 10th and 17th August 2020.  I'd only identified this species once before (2018) but I think I have overlooked it in the past (as I think I did for what was almost certainly another one on 8th August 2020 - misidentified at the time due to a contradiction in the reference I was using regarding the width of pale at the base of the cuneus).

Psallus flavellus - None.  I identified this species in my garden in 2018.


Psallus haematodes - One at the meadows on 22nd August 2019 and one in the garden moth trap on 1st August 2020 - I've had 1-2 here before in 2016 and 2018.

Psallus perrisi - I identified 3 of these from my garden and 1 from the meadows in 2018 but haven't found any males since.  Some female perrisi/wagneri were found in 2020 - see under wagneri below.


Psallus varians - I had thought this was the commonest Psallus here in the past but in 2020 when I realised I'd been confused by the contradiction in my reference over Psallus falleni, I reviewed my previous records (only from photos as I didn't keep the specimens).  I think some of them are probably fine but several look like they may have been misidentified and so I'm now considering the latter unproven.  Anyway, I had identified 5 here (all to light) in 2019 but am now only leaving one of those records standing, that from 1st June.  I've also reviewed the 11 I had recorded here in 2018 and deleted 5 of those (but the other 6 look good).  Some of those I've deleted may well have been correctly identified but others were probably falleni.  Only one identified here in 2020, on 24th June, and I think I may have identified that one before realising the problem with falleni, so am excluding that one from the records too (it looks a bit doubtful from the photo).  The same applies to my first record from the meadows in 2020 but those on 27th May and 23rd June were processed after I was aware of the problem and I think these are fine (the latter was a male, gen detted).

Psallus wagneri - Female bugs at the meadows on 27th May (3) and 13th June 2020 were either this species or Psallus perrisi.  I did have a confirmed perrisi here in 2018 but the only fully identified record of this duo from the meadows in 2020 was my first confimred male wagneri, on Broom (under Oak) on 1st June.

That night Dave and I headed back to Frost's Common, a site we'd been planning to trap at for a long while.  The Norfolk Moth Survey event there was a wash-out so we thought we'd try again on a better night.  Conditions weren't ideal but we managed 47 species including a few mildly interesting ones: Oak Carl Tischeria ekebladella, 3 Brown Birch Slenders Parornix betulae, 2 Golden Argents Argyresthia goedartella, Bird-cherry Ermine Yponomeuta evonymella, Birch Ermel Swammerdamia caesiella, Chamomile Conch Cochylidia implicitana, Chequered Fruit-tree Tortrix Pandemis corylana, 2 Common Marbles Celypha lacunana, 3 Birch Marbles Apotomis betuletana, Rush Marble Bactra lancealana, Small Birch Bell Epinotia ramella, 2 Pearl Veneers Agriphila straminella, Barred Grass-veneer Agriphila inquinatella, 6 Ground-moss Greys Eudonia truncicolella, 3 Brown China-marks Elophila nymphaeata, 7 Ringed China-marks Parapoynx stratiotata, 3 Small China-marks Cataclysta lemnata, 3 Mother of Pearls Pleuroptya ruralis, Meal Moth Pyralis farinalis (only my second ever), Double-striped Knot-horn Cryptoblabes bistriga, Dotted Oak Knot-horn Phycita roborella, 2 Maiden's Blushes, 3 Common Carpets, Yellow Shell, 2 Purple Bars, 5 Green Carpets, 5 Double-striped Pugs, Yellow-barred Brindle, 5 Brimstone Moths, 2 Common Waves, 3 Light Emeralds, Poplar Hawk-moth, Dingy Footman, 2 Buff Footmen, 3 Common Footmen, Shuttle-shaped Dart, 4 Flame Shoulders, Large Yellow Underwing, Lesser Yellow Underwing, Lesser Broad-bordered Yellow Underwing, Setaceous Hebrew Character, 2 Common Wainscots, Svensson's Copper Underwing, Burnished Brass, Spectacle, 10 Straw Dots and 2 Snouts.

We found a newt at each of the lights which I am having some trouble identifying.  They are most likely Smooth Newts - I don't think there are all that many confirmed records of Palmate Newt in Norfolk from what I can glean.  The references I've got and those I've found on the internet seem to focus on adults for identification, some mentioning that immatures require more caution but not elaborating any further. Several references refer to the unspotted throat as a key feature for Palmate Newt but even some of those include photos of Smooth Newts with unspotted throats, so clearly this is not diagnostic!  The upperpart markings appear to be very variable and overlapping between the tweo species as are the spots below and the pattern of orange underneath.  I get the impression, but if someone can confirm that would be great, that the presence or absence of pale tubercles on the bottom of the feet (present on Palmate) is the most reliable feature.  Having had this problem before I recalled that spots on the soles of the feet were relevant and so took photos as I couldn't remember the detail of what to look for.  Sadly my photos aren't perfectly clear (it's quite hard to get a newt to stay still upside down without manhandling it) and there are some pale spots in some images that aren't in others, suggesting that they may be grit or dirt.  At least one of them does seem to have one or two pale spots on the sole in the same place in every photo suggesting it may be a real feature and suggesting that they might be Palmate Newts.  However, I'm not convinced and suspect they are in fact female and/or immature Smooth Newts.  If you are any clearer on these things please do get in touch!
