This chart shows that in 2016 UK observations of G. laticinctus recorded at NBN Atlas became more frequent than observations of G. quadrifasciatus:

There is not much information about these two species online, so I have collected some links.

For differences between the two species, see:

  quadrifasciatus yellow band occupying 1/4 of 2nd dorsal plate and face with small yellow patches.
  laticinctus yellow band occupying not less than 1/3 of 2nd dorsal plate and face largely yellow.
  

• G. laticinctus: https://www.naturespot.org.uk/species/gorytes-laticinctus
  
  9 to 13mm. This is one of several very similar wasps in the family which require a specimen or excellent macro photos to identify. The first dorsal plate is straight-sided rather than bulged and the yellow on the second dorsal plate occupies not less than 1/3 of its length. The face is largely yellow, extending above the level of the antennal insertions.

The first time I saw this wasp was on 27 August 2022, in the Herb Garden in Battersea Park. https://uk.inaturalist.org/observations/132809120 . It was on Goldenrod (Solidago}. The next day I saw it again but I did not manage to get a photo.

I saw it again 2 weeks later, on 10 September 2022, and this time I was able to take better photos. https://uk.inaturalist.org/observations/134427963

The first sighting in the United Kingdom, in Greenwich, SE London, had been in August 2016.

By the time of my first sighting there had been 6 records on Inaturalist. https://uk.inaturalist.org/observations/181595203

This is the link to all the 15 records on Inaturalist, 8 of which were in Greater London and the others in SE England (Thames Estuary at Southend-on-Sea) and the South Midlands (near Royal Leamington Spa). https://www.inaturalist.org/observations?order_by=observed_on&place_id=6857&taxon_id=203340&verifiable=any
6 of these records were in 2022 and 5 were in 2023.

There are 15 records on GBIF, of which 12 are from Inaturalist.

The other three records on GBIF are the only three records which are on NBN Atlas.

There are 7 United Kingdom observations of this Harvestman on Inaturalist, all in Greater London, with the first being on 14 May 2022. https://www.inaturalist.org/observations?place_id=6857&taxon_id=347952

6 observations were made on the same wall in a domestic garden near Epsom in 2022, 2023 and 2024. See https://www.inaturalist.org/observations/205411433

The other observation was made in Battersea Park, Central London, on 17 April 2022. It was motionless on a leaf of Smyrnium olusatrum. https://www.inaturalist.org/observations/155350780 Despite many searches thereafter, it has not been seen there again. The initial identification as D. granifera was made by @ldvn, an Opiliones researcher in France.

All observations were of females, and were in April and May. The same records are on GBIF:
https://www.gbif.org/occurrence/search?taxon_key=4553452&gadm_gid=GBR
There are no records on NBN Atlas and the species is not listed there.

Description of Phoridae: https://en.wikipedia.org/wiki/Phoridae

There is an area of trees, long grass and rough vegetation in the north-east corner of Battersea Park (beside the River Thames in Central London) where the vegetation has been allowed to grow longer. I have been able to see a number of unusual or under-recorded species in this area, in particular on the Daucus carota. The area is approximately 50 metres x 50 metres.

Since 1 January 2024 I have posted 129 observations of 79 species in this area, mostly of invertebrates. 65 are insect species. In addition to these there will have been other species which I have not recorded this year because I have recorded them in earlier years. 45 of the 79 species are Research grade.

Here is a link to my observations since 1 January 2024:

These are the most interesting:

• Holopyga generosa, a blue and red cuckoo wasp with 20 records on Inaturalist/GBIF
• Eriothrix rufomaculata , Red-spotted parasite fly
• Maleanargia galathea, Marbled White butterfly
• Ochlodes sylvanus, Large Skipper butterfly
• Manioloa jurtina, Meadow Brown butterfly
• a nursery web of Pisaura nobilis, the Nursery Web Spider
• a Misunema vatia, Golden-rod Crap Spider, with flies sharing its Honey Bee prey

Since 30 Augst 2022 I have posted 282 observations of 151 species in this area. 92 species are Research grade. https://www.inaturalist.org/observations?nelat=51.48279948840825&nelng=-0.15094337274332625&order_by=observed_on&place_id=any&subview=grid&swlat=51.48209793833795&swlng=-0.15216646005411727&user_id=cf125
