Sphingidae Larvae

Sphinginae subfamily

Sphingini tribe: Manduca quinquemaculatus WO, the Five-spotted Hawkmoth The caterpillars are called Tomato Hornworms and each has a black horn at the end of the abdomen. Larvae feed on potato, tobacco, tomato, and other plants in the nightshade family (Solanaceae). Sphinx chersis BAMONA, the Northern Ash Sphinx or Great Ash Sphinx: The larvae are pale bluish green. The head has a pair of yellow lateral bands meeting at the apex. The oblique, lateral stripes are pale and bordered anteriorly with a darker green. Larval hosts are ash, lilac, privet, cherry, and quaking aspen.doubtful Sphinx drupiferarum WO, the Wild Cherry Sphinx Larvae hide in the day and feed primarily on cherry, plum, and apple at night. Larvae have been found on Amelanchier nantuckensis in Massachusetts and have been reared to pupation in Michigan on Prunus serotina. Note purple oblique lines. Sphinx perelegans WO, the Elegant Sphinx: The basic body colour can be either glaucous or apple-green, without the earlier body tubercles. The oblique side stripes are white, edged with purple. The horn is sky blue. The spiracles are pale orange and the anal flap is edged with yellow. Sphinx vashti WO, the Snowberry Sphinx Larvae feed on the common snowberry (Symphoricarpos albus) and on coralberry (S. orbiculatus). Note the two golden lines of slightly raised bumps, one just behind the head, the other on the thorax. Smerinthini Tribe: Pachysphinx occidentalis WO, the Big Poplar Sphinx Larvae feed on cottonwood and poplar (Populus) and willow (Salix). Larvae are very chunky with little to distinguish them from Pachysphinx modesta. Paonias excaecata BAMONA, the Blinded Sphinx Larvae accept willows, birches, and cherries. I have also found them in the wild on oak in eastern Canada. Skin is quite granulous. Paonias excaecata, parasitized, feeding on plum, White Salmon, September 7, Candice Keller. Paonias myops WO, the Small-eyed Sphinx Wild cherry species are the favorites as larval foodplants, but eggs will also be deposited on birches and other forest trees. There are varying degrees in the amount of red markings along the sides. Smerinthus ophthalmica WO: Ophthalmica larvae resemble cerisyi larvae, both being pale green, with granular skin, pale lateral diagonal lines, faint red spiracular circles, and very pale longitudinal lines running from head to more pronounced anal diagonal line. Larvae have green heads bounded dorsally with pale yellow inverted "V". Note blue horn. Macroglossinae subfamily Dilophonotini tribe: Hemaris thetis BAMONA, Larval host plants include Snowberry (Symphoricarpos), honeysuckle (Lonicera), Coralberry, viburnums, high bush cranberry and hawthorn (Crataegus). Horn is black with a slightly lighter base. This western species was formerly classified as H. diffinis or H. senta. Those species west of the Continental Divide are now classified as H. thetis. Listed as diffinis on BAMONA Macroglossini tribe: Hyles gallii BAMONA, the Bedstraw Hawk Moth or Gallium Sphinx This species is not reported in Chippewa, but it has been recorded in eastern Wisconsin counties. I suspect it is present. Larvae come in black and in brown forms and often feed on Epilobium (fireweed). Hyles lineata WO, the White-lined Sphinx Larvae are highly varied and feed on a great diversity of plants including willow weed (Epilobium), four o'clock (Mirabilis), apple (Malus), evening primrose (Oenothera), elm (Ulmus), grape (Vitis), tomato (Lycopersicon), purslane (Portulaca), and Fuschia. All larvae seem, however, to have the red/black swellings split by dorso-lateral lines. Proserpinus clarkiae WO, Clark's Sphinx, Larvae feed on elegant fairyfan (Clarkia unguiculata) in the evening primrose family (Onagraceae). Proserpinus flavofasciata WO, Yellow-banded Day Sphinx, Larvae feed on willow weed (Epilobium) and possibly thimbleberry (Rubus parviflorus).
