All Insects do not undiTgo the sjiim- chanK's ; neither art- they alike inanalo((oU'^i>tate>. 

 Thuii the caterpillar of our hutterflles wraps itx-lf in it» inantl(>, where It silently under- 

 goes itifrluinge ; but the Kms<iho|>|KT comes fn>m the egcan luiniatun- insect, but with the 

 general f<irni of the jHTfi-ct nninial, nnd hops alxtnt with the nuiinunts of wings ui«>n It* 

 back. As it i;n>ws rapidly, it out>rn>ws its skin, which it fn <juentl) cn-sts, like the lan'a of 

 the buttcrtly : its win-^s continue to gn.w, and the Uxly to increns<- ; the partial wings 

 ktH'p pace with thes«' clianijes, till at last they are |>erfectitl, and the animal has r(*ached 

 its {KTlect slate without havin;; lo-t its arti\ ity durint; its jK-ri' d of un>wlh. llie gra^s- 

 hop|MT, then, never pasMs into the inactive pupa state ; and In this its metamorphosis is 

 similar to bugs, and dissimilar to Ix-etles and caterpillars. 



There Is another difference in the historj- of insect life, which is interesting : it is not 

 the inhabitant of the sjime medium ihn'Ugh life. It may l>egin Its caner in the water, nnd 

 end It in the air : the muMpiilo is an example. Who has not ol»<erve<l the wiggler in 

 stagnant water, and in our cisterns l It is the miL^quito enjoying its water-life to the full. 

 When till' time arrive* for its change, it ris«~i to the surface, bursts its mantle, thrusts up 

 Its heail and «i>reads its wint's, while with its feet it rests still ujx.ii its ca«t-off mantle, then 

 ris*** buoyant from its linking Iwirk, and Hies away in lriumi>h from the eh-ment which 

 gave it birth. 



E<iually remarkable an- th«' ap|H'tites of the insect in its larva nml in it* |>erf<ct slate. 

 Thus the larva, or, as it is usually cnlle<l, the mannof, sjK^rts and feeds upon the putrid 

 mas* ; but the fly, which si>rings fn>m its mantle, seeks thehoney of our tabic : su rnrious 

 art- the forms ami manners of ins^-et lifi-. The cater]>illHr, grub nnd maggot go thn>ngh the 

 three stages, or undergo a complete metamorphosis ; pas>ing thn>ugh the three |4«ri<<l» 

 which are kiiown as the caterpillar, pu|>j|. and imago. or jH-rfi-ct slaire. The last is the only 

 p4-ri<Ml which is given thi-m to continue their kind and zenenilions : in man) it is transitnt 

 as the tb-4-ting day, ami s<-«'ms designetl onl\ for fulflllim: the law of incrrax- : which, when 

 fulfilled, the insect dies
