Hickory shuck worm 



Ejiar))ion!a caryaiui l-'itch 



A slender, white caterpillar about ;'» inch long, mines hickory shucks causing them 

 t<i abort and f.iU prematurely. 



This little miner of thi; hickory shucks or husks is very common in 

 New ^'(lrk Stiitc and so far as our observations go, its operations have b(!cn 

 confined to the husk or shuck envelojjing thi- nut. Dr Shinier states that 

 in Illinois the larvae live in the- nut of th(- hitternut hickory, Carya 

 a mar a, destroying its interior antl causing it to fall. Dr Fitch has placed 

 on record the statement of Louis Potter of Kaston N. Y., to the effect that 

 this insect was so numerous in his section in 1X56, tiiat several of the 

 hickory trees scarcely produced a single nut. Accortling to Dr Shinier, the 

 moths appear the latter [lart of November, hibernate in this stage and live 

 till some time in June, when they deposit eggs on the yoimg nuts. Dr bitch 

 states that sjjecimens of this insect were received by him from Maston 

 N. ^'., in April, with a letter .saying that the insect jnipatetl about the first 

 of l-'ebruar)-, the moth emerging the latter ])art of that month. Dr Pack- 

 ard recortls taking unrul)bed specimens of this moth Ma\' 20, in a grcnvtii of 

 \oung hickories at Providence. These; two records seem to indicate that 

 some of the insects hibernate in the lar\ al or pupa stage. 



Description. The moth h.is been described as follows, by Dr I'itch : 



Sooty black, the lore wings with reflections of tawny yellow, blue and 

 purple ; their outer edge black, with oblicpie triangular whitish streaks placed 

 at e(|ual distances a|)art. A vei'y oblicpie faint siKery blue streak e.\tends 

 inward from the |)oints of two of th(fse white streaks, namely, the fourth 

 and sixth ones from the tip of the wing; while the usual white sjjot on the 

 inner margin of the wings is wanting. F'^-xpanse of wing.s, .6 inch. 



Acorn weevil

.\ weevil, with a remarkably long slender curved beak, u( curs on acorns or may be 

 bred from white legless grubs within them f)r other niUs. 



This species was met with in small numbers wln-n collecting in | ime
