Euheptaulacus sus
Key Details
| Taxonomic Groups: | Invertebrate > insect - beetle (Coleoptera) > Scarab beetle or ally |
| 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: | Euheptaulacus sus |
| UKSI Recommended Authority: | (Herbst, 1783) |
| UKSI Recommended Qualifier: | (none specified) |
| Red List Citation: | Lane and Mann, 2016 |
| Notes on taxonomy/listing: | (none) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Only 4 sites since 1990; formerly more widespread. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Euheptaulacus sus occupies patch habitats not necessarily created through habitat management. |
| 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: | Yes |
| Justification: | Yes, if this involved grazing animals in the absence of endectocides on unimproved pasture. Its precise breeding requirements are unknown so a mosaic of different swards heights and bare ground could be beneficial to allow a dung to fall in a variety of situations. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Life history factor/s |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: |
Key Actions
Key Action 1
Proposed Action: Implement year round low intensity cattle or sheep grazing at sites across the key landscapes. Do not use endectocides. In winter livestock should not be fed in silage, maize or soya since this affects the quality of the dung and its nutritional value to coprophagous invertebrate larvae.
Action targets: 5. Remedial action identified
Action type: Habitat management
Duration: >10 years
Scale of Implementation: ≤ 5 sites
High priority sites: Northam Burrows SSSI, Sandwich Bay SSSI, Lakenheath, Hockwold cum Wilton
Comments:
Key Action 2
Proposed Action: Targeted non-lethal monitoring to assess population trends in response to amended livestock management techniques
Action targets: 6. Recovery solutions trialled
Action type: Targeted monitoring
Duration: 3-5 years
Scale of Implementation: ≤ 10 sites
High priority sites: Northam Burrows SSSI, Sandwich Bay SSSI, Lakenheath, Hockwold cum Wilton
Comments: monitoring of Action 1 results
Key Action 3
Proposed Action: Field study to establish exact habitat requirements for E. sus to breed successfully and understand its dispersal capability.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: ≤ 10 sites
High priority sites: Northam Burrows SSSI, Sandwich Bay SSSI, Lakenheath, Hockwold cum Wilton
