Papilio ophidicephalus zuluensis

Assessor: Dave Edge

Sensitive in 2010
No
Family
Papilionidae
Reason for the sensitivity status
African Papilio are known to be traded regularly and lucratively. As this species has a vulnerable population size and a slow population growth rate, exploitation would not be withstood. Releasing data on this species can exacerbate threat and vulnerability.
This species is either similar to another sensitive species or belongs to a group containing sensitive species, and is extremely rare in the wild. The localities of wild populations need to be protected to avoid loss to exploitation, which, due to its rarity, could drive the species to extinction within a very short time.
Exploitation extent
Uncertain - No data exists yet showing that this species is exploited in the wild, however it has one or more relatives or look-alike species (found in South Africa or globally) that are known to be utilised. This species has a similar life form or other relevant traits to its exploited relative(s), making it highly likely that it would be exploited for the same purposes.
Population vulnerability
Population is vulnerable: size is <= 2500 mature individuals OR the number of known subpopulations is <= 5 OR range is <= 100km2 OR species at risk of localised extinctions
Justification and references

A full conservation assessment of this taxon was done according to IUCN methodology and it was Red Listed as "Least Concern – Rare (Restricted Range)". The results are published in:

MECENERO, S., BALL, J.B., EDGE, D.A., HAMER, M.L., HENNING, G.A., KRÜGER. M., PRINGLE, E.L., TERBLANCHE, R.F. & WILLIAMS, M.C. (eds) 2013.

The red listing also appears on SANBI's Red List website:

Targeted demographics
Unknown.
Regeneration potential
This species has a slow population growth rate, or the growth rate varies depending on habitat, and there is a poor chance the wild populations will recover from exploitation OR a collector might feasibly harvest the entire extant population removing the chance of subsequent recruitment.
Justification and references

It can be seen by studying the references that this butterfly has always had a restricted range and it is never found in great numbers. It can be inferred that it has a slow population growth rate and would not be able to withstand exploitation.
