Setodes punctatus
Key Details
| Taxonomic Groups: | Invertebrate > insect - caddis fly (Trichoptera) > Caddisfly |
| Red List Status: | Vulnerable (Not Relevant) [VU(nr)] |
| D5 Status: | Included in the baseline Red List Index for England (Wilkins, Wilson & Brown, 2022) |
| Section 41 Status: | (not listed) |
| Taxa Included Synonym: | (none) |
| UKSI Recommended Name: | Setodes punctatus |

| UKSI Recommended Qualifier: | (none specified) |
| Red List Citation: | Wallace, 2016 |
| Notes on taxonomy/listing: | (none) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Currently found in only two rivers |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | It appears to be expanding its range but that may be just back to a mid 20th century distribution. There is lack of knowledge of its micro-habitat distribution and that may be affected by flow as well as water quality. |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | No |
| Justification: | General habitat diversification as in many river plans may help this species but it probably has very specific requirements |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Relict or natural rarity |
| National Monitoring Resource: | Combination - insufficient |
| Species Comments: | The EA surveys the sites but the adults also light trap |
Key Actions
Key Action 1
Proposed Action: Supplement EA monitoring programme by adding focussed surveys in June to estimated population size at sites on the Severn, such as Bewdley and Montford Bridge and Hereford and Redbrook on the Wye so a future decline could be noticed. Note micro-habitat at same time.
Action targets: 3. National Monitoring Plan agreed and implemented
Action type: Targeted monitoring
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: R. Severn at Bewdley & Montford Bridge
Comments: Population size not known and micro-habitat not known so ensuring there is plenty of that cannot be done.
Key Action 2
Proposed Action: Undertake a detailed survey across the River Severn at Bewdley to establish the microhabitats the species is using which may result in proposing an action to increase that habitat.
Action targets: 4. Autecology and pressures understood
Action type: Status survey/review
Duration: 2 years
Scale of Implementation: 1 site
High priority sites: River Severn, Bewdley
