  noted 
  that 
  the 
  larvge 
  seemed 
  to 
  adapt 
  themselves 
  very 
  readily 
  to 
  

   environment, 
  and 
  that 
  the 
  purplish-red 
  larvae 
  were 
  found 
  mostly 
  on 
  

   the 
  flowers, 
  or 
  reddish 
  parts 
  of 
  the 
  stem, 
  and 
  the 
  green 
  larvae 
  on 
  the 
  

   green 
  parts. 
  Hofmann 
  notes 
  that 
  " 
  the 
  larva 
  lives 
  in 
  July 
  on 
  the 
  

   unripe 
  seed-capsules 
  of 
  Aquilegia 
  vulgaris, 
  boring 
  into 
  the 
  capsule 
  

   through 
  a 
  roundish 
  hole, 
  and 
  penetrating 
  therein 
  as 
  far 
  as 
  the 
  first 
  part 
  

   of 
  the 
  body." 
  Zeller 
  observes 
  that 
  he 
  found 
  the 
  larvae 
  also 
  on 
  Geranium 
  

   nratense, 
  devouring 
  the 
  blossoms 
  and 
  seeds, 
  as 
  well 
  as 
  on 
  Erodium 
  

   cicutarium 
  (Stett. 
  Ent. 
  Zeitg., 
  1878, 
  p. 
  163). 
  Frey 
  records 
  the 
  larvae, 
  in 
  

   June, 
  on 
  Stachys 
  sylvatica, 
  then, 
  four 
  or 
  six 
  weeks 
  later, 
  on 
  the 
  seeds 
  of 
  

   Aquilegia 
  vulgaris. 
  Boll 
  notes 
  the 
  finding 
  of 
  larvae 
  in 
  the 
  bloom 
  of 
  

   Stachys 
  sylvatica 
  at 
  Bremgarten. 
  Bankes 
  observes 
  that 
  the 
  larvae 
  feed 
  

   on 
  the 
  flowers 
  and 
  unripe 
  seeds 
  of 
  Stachys 
  sylvatica 
  in 
  the 
  Isle 
  of 
  

   Purbeck. 
  In 
  Pomerania, 
  the 
  larvae 
  are 
  found 
  eating 
  the 
  seeds 
  of 
  

   Aquilegia 
  (Paul 
  and 
  Plofcz),and 
  in 
  the 
  Hamburg 
  district, 
  flowers 
  of 
  Stachys 
  

   sylvatica 
  (Sauber), 
  also 
  in 
  Silesia, 
  although 
  they 
  feed 
  as 
  well 
  on 
  the 
  flowers 
  

   of 
  Aquilegia 
  vulgaris 
  (Wocke) 
  ; 
  in 
  the 
  kingdom 
  of 
  Saxony, 
  the 
  larvae 
  

   are 
  found 
  on 
  Euphrasia 
  officinalis 
  and 
  Stachys 
  palustris, 
  as 
  well 
  as 
  S. 
  

   sylvatica 
  (Schiitze) 
  ; 
  in 
  Bavaria, 
  they 
  are 
  to 
  be 
  taken 
  at 
  the 
  beginning 
  

   of 
  July, 
  usually 
  in 
  some 
  numbers, 
  when 
  present 
  at 
  all, 
  clearing 
  out 
  the 
  

   contents 
  of 
  the 
  green 
  seed-vessels 
  of 
  Aquilegia 
  vulgaris, 
  and 
  going 
  to 
  

   others 
  when 
  these 
  are 
  emptied 
  ; 
  the 
  larvae 
  will 
  also 
  eat 
  the 
  green 
  pupae 
  

   if 
  they 
  meet 
  with 
  them 
  (Schmid) 
  ; 
  in 
  Wiirtemberg, 
  the 
  larvae 
  are 
  to 
  be 
  

   found 
  in 
  July 
  and 
  in 
  the 
  autumn, 
  feeding 
  on 
  the 
  seeds 
  of 
  Aquilegia 
  

   and 
  the 
  flowers 
  of 
  Stachys 
  sylvatica, 
  in 
  a 
  delicate 
  web 
  (Steudel 
  and 
  

   Hofmann). 
  Dyar 
  records 
  (Proc. 
  Unit. 
  Sta. 
  Nat. 
  Mus., 
  xxvii., 
  p. 
  922) 
  that,, 
  

   at 
  Kaslo, 
  in 
  British 
  Columbia, 
  he 
  found 
  larvae 
  in 
  the 
  red 
  bracts 
  of 
  the 
  

   high 
  bush-honeysuckle 
  (Lonicera 
  involucrata), 
  eating 
  holes 
  in 
  the 
  young 
  

   fruit 
  through 
  the 
  bracts, 
  and 
  destroying 
  the 
  fruit. 
  Frey 
  says 
  that 
  the 
  

   larvae 
  occur 
  in 
  July, 
  in 
  Switzerland.
