Hyles tithymali caterpillar
|[Note Guidelines] Photographer's Note|
|HYLES TITHYMALI (Boisduval, 1832)|
GB: Barbary Spurge Hawkmoth, F: Sphinx du Tithymale
LARVA: Full-fed, 70--80mm. Almost identical to those of subsp. mauretanica and subsp. deserticola.
Young larvae are black at first, turning to olive black after feeding, with the final colour pattern appearing in the third or fourth instar. Fully grown, it is quite unlike any colour form of H. euphorbiae, more closely resembling certain varieties of H. livornica. In some individuals, the white eye-spots may be flushed with red.
Eggs and small larvae are generally found on small plants of Euphorbia regis-jubae (van der Heyden, 1991). Larger larvae move to and then feed quite openly on the taller, more mature bushes, alternating frenzied bouts of feeding with long stretches of basking (Pittaway, 1976). They may occur in such numbers as to defoliate large areas of hostplant. In midsummer some individuals become fully grown in 20 days.
Being continuous-brooded, various stages of development can be found simultaneously on the same plant, although larvae are scarce from July to October (van der Heyden, 1991).
Major Hostplants. The shrubby Euphorbia regis-jubae (van der Heyden, 1988) and Euphorbia lamarckii [syn. E. broussonetii & E. obtusifolia]. (It should be noted that as E. regis-jubae is confined to Gran Canaria, Fuerteventura and Lanzarote, E. lamarckii is utilized on the other islands.)
