Managing lycaenid populations Various management plans for particular Lycaenidae have been produced, and these have several elements in common: habitat security; the need for management based on sound biological and ecological understanding of the target species; and the need for an understanding of the endangering processes. Increasing public awareness of the particular lycaenid is also commonly seen as important. The processes needed are well exemplified in a 'flow-chart' produced by Arnold (1983a) for Smith's Blue (Euphilotesenoptessmithi(Mattoni)) in California and augmented in his Recovery Plans for the Lotis Blue (Lycaeides idas lotis (Lintner) and other species (USFWS 1984, 1985), and this has been used as a basis for the scheme outlined in Table 7. It is clear from this that the basic information necessary to formulate sound management for any ecologically sensitive species cannot be gathered instantly. All too often the time available is insufficient once a decision has been taken to develop a habitat containing a threatened species or population. The approach of 'Population Viability Analysis' (sometimes, 'Population Vulnerability Analysis'), PVA, is receiving substantial attention in assessing conservation needs of vertebrate animals. In general, the detailed demographic and reproductive data needed for such predictive modelling are not available for extending this approach to invertebrates. However, a North American lycaenid, the Karner Blue (Lycaeidesmelissa samuelis Nabokov) has recently (April 1992) been the focus of the first specialist workshop held to appraise an insect in this context. This species lives in fire-successional vegetation, and the metapopulations are associated with local extinctions and recolonisation or habitat shifts linked with climate and fire regimes (Cushman and Murphy, this volume). The outcome from this workshop may mark a substantial augmentation to current methods of formulating management programmes for insects of conservation concern. Ex situ conservation Table 7. A pro-forma scheme for species-orientated conservation of Lycaenidae (after Arnold 1983a). 1. Preserve, protect and manage known existing habitat to provide conditions needed by the species. (a) (b) (c) (d) Preserve: prevent further degradation, development or environmental modification. Steps (some or all): (i) Cooperative agreements with landowners/managers. (ii) Memoranda or undertakings. (iii) Conservation easements. (iv) Site acquisition (purchase/donation): private land. (v) Site reservation: public land. Maintain larval and adult resources at known habitat(s). Steps (some or all): (i) Minimise use of toxic substances: herbicides, pesticides. (ii) Minimise uncontrolled intrusion by humans: trampling, off-road vehicles, etc. (iii) Minimise intrusion by domestic stock: cattle, horses, sheep, etc. (iv) Minimise exotic vegetation planting. (v) Minimise removal of native vegetation, unless controlled. The controlled harvesting and ranching of Papilionidae to reduce pressure on natural populations and supply collector needs has proved to be an important conservation avenue for this group. It probably will never be achievable (or, indeed, needed) for lycaenids on any large scale, despite their uniqueness and vulnerability and their geographical overlap with areas where Papilionidae are also vulnerable. However, rearing of particular rare species in captivity does have some potential for augmenting field populations and for effecting translocations. The Atala Hairstreak, Eumaeus atala, has proved to be relatively easy to rear in captivity, and this practice is pursued by several butterfly houses in Britain using stock from Florida (Collins 1987a). Some success has been obtained with attempts to start new colonies of E. atala in the wild, and although the species continues to be regarded as vulnerable to habitat loss it has become more widespread in recent years (Lenczewski 1980). Some Japanese Theclini may be reared relatively easily from eggs collected in the field, and eggs of species which are otherwise very hard to collect have been found (Kuzuya 1959). The larval stage lasts for 3–4 weeks, as does the pupal period, and the only major problem in rearing was a tendency for older larvae to be cannibalistic. Unlike most other butterflies, captive rearing of lycaenids may need to incorporate provision for ants, often of particular species for any given lycaenid, as well as foodplants. Propose critical habitat (U.S.). If necessary, clarify taxonomic status of target lycaenid in habitat and, where known, outlier or other populations. 18 Continued...
