Anthicus bimaculatus
Key Details
| Taxonomic Groups: | Invertebrate > insect - beetle (Coleoptera) > Darkling 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: | Anthicus bimaculatus |
| UKSI Recommended Authority: | (Illiger, 1801) |
| UKSI Recommended Qualifier: | (none specified) |

| Notes on taxonomy/listing: | (none) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Only a small number of recent records and appears to have declined/disappeared from sites where it was formerly commonly encountered. However, this is a small, easily overlooked species and under-recording is an important factor. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Taxon thought now never to have occurred in England; the entity thought to be it is an alien |
| 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: | Seems to rely on plant litter on sandy soils near the coast and has been suggested that maintaining dynamic sandy habitats on the coast could benefit this species. |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Unknown |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Only a small number of recent records, but this is a small, easily overlooked species. Very little known of the ecology of the adults and larvae. |
Key Actions
Key Action 1
Proposed Action: Define autecology of larvae and adults at known sites.
Action targets: 4. Autecology and pressures understood
Action type: Scientific research
Duration: 3-5 years
Scale of Implementation: ≤ 5 sites
High priority sites: The Crumbles, nr Eastbourne, but this population may have been lost
Comments: What are micro-habitat preferences and diet of the adults and larvae? What are the dispersal abilities of the adults? Reliable identification of larvae may only be possible using molecular tools.
