Tentiform mine.................................................................................................... Cremastobombycia lantanella Busck ¶ ( Gracillariidae , Lithocolletinae ), all Hawaii islands, host: Lantana spp. - Short, tortuous linear, spiral mine, about ~ 30 mm length...................................................... 2 - Long (tortuous) linear or blotch mine..................................................................... 3 2. Mature larva (3rd~ instar) is external feeding, nibbling the leaf tissue and skeletonizing it.. Bucculatrix thurberiella Busck ¶ ( Bucculatricidae ), Oahu, host: Gossypium tomentosum (endemic Hawaiian cotton). - Mature larva is leaf-mining, and mines leaf tissue forming several blotch mine............................................

First instar larva is sap-feeding, forming whitish linear mine................................................... 4 - Larva tissue-feeding, forming linear or serpentine to blotch mines; cocoon usually situated outside of mine......................................................................... Philodoria Walsingham ( Gracillariidae , Ornixolinae ) 4. Cocoon situated outside of mine, usually on surface of leaf.................................................... 5 - Cocoon situated within end of mine, larvae mining leaves of Rutaceae ( Citrus spp.)................................................................................... Phyllocnistis citrella Stainton ( Gracillariidae , Phyllocnistinae ) 5. Late instar larva tissue feeding, cones created by rolling leaf.................................... Caloptilia H̹bner ¶ - On Diospyros hillebrandii and D. sandwicensis (Ebenaceae) , Oahu.................... C . mabaella (Swezey) ( Fig. 73D ) - On Myrica faya (Myricaceae) , Hawaii (Big Island)............... Caloptilia sp. nr. schinella † (= coruscans (Walsingham)) - Late instar larva tissue feeder in blotch mine elongated along the leaf edge; the leaf edge at the blotch is narrowly folded down; on Terminalia catappa (Combretaceae) , Oahu.................................................... Ketapangia sp. * This key, where only mines and/or cocoons have been examined, but not larvae or adults, can serve only as a partial aid to determination. ¶ Zimmerman (1978a) ; † Markin (2002) ; Perreira and Yee (2016) § .
