Vandrende Rosengren (Extatosoma tiaratum) Familie: Phasmatidae Orden: Vandrende Pinde (Phasmatodea)

Størrelse:  12-13 cm (hunner). Udbredelse:  New Guinea og Ø. Australien (Queensland, New South Wales). Levested:  Buske og træer. Føde:  Blade fra planter som brombær, eukalyptus, tjørn, eg, ildtorn, hindbær og rose. Ynglebiologi:  Meget aktiv i de første nymfestadier, hvor nymfer tilsyneladende søger op i bevoksningen for at nå de højeste grene. Aktivitet og adfærd:  Hænger ofte med ryggen nedad i bladhanget, med bagerste del af kroppen bøjet op over ryggen som et krøllet blad. Hannerne flyver gerne, hvis de forstyrres eller når de søger efter hunner. Kønsforskelle:  Hunnerne er større end hannerne. Variation:  Arten er meget variabel i farven, som kan være brunlig, rødlig, grønlig eller gråbrun. Status:  Artens status kendes ikke med sikkerhed, da man endnu ikke har tilstrækkelig viden om dens forekomst i naturen.
