    THE INTRODUCTION, pp. 3-11, explains the book's scope, wi tha basic sur:vey of insect classification, anatomy, l i fe-cycles,col lection and conservation.THE KEY, pp. 12-15, cross-referenced to the main text, shouldenable one to p lace any insect in i ts cor rect group.THE INSECTS are arranged scienti f ical ly from si lverf ish tobeet les , cover ing a l l orders found in Europe, ( l is ted on p. 11) , andal l major fami l ies .

    rTHE ILLUSTRATIONS - over 2300 of them - cover the speciesmost likely to be noticed, for their size, colour, habits, frequencyor associat ion with humans. Sexes are indicated where theynoticeably dif fer, and sizes where the picture is not l i fe-size.THE TEXT-- nowwholly revised and updated -stresses importantpoints not obvious from the pictures; aspects of behaviour, foodor habitat where useful for identi f icat ion; European distr ibutionand months of appearance. There are brief introductions to eachorder and larger fami ly , w i th longer ones on:

They are represented by immensep o p u l a t i o n s - p e r h a p s 1 0 m i l l i o n i n d i v i d u a l s i n a s i n g l e t e r m i t e c o l o n y , a n d60,000 spr ing ta i l s in a square met re o f tu r f . In th is respec t they are cer ta in lyexceeded by the nematode worms, w i th 20 mi l l ion or more to the square met re insome so i l s and more than 90 ,000 ind iv idua ls hav ing been ex t rac ted f rom a s ing lero t t ing app le ; bu t nematodes do no t exh ib i t any th ing l i ke the fan tas t ic var ie ty o finsec t l i fe .

    The European insec t fauna numbers about 100.000 known spec ies , w i th a g rea trange o f s ize and fo rm. Cand ida tes fo r the la rges t o f them inc lude the Gian tPeacock Moth (p. 1381, Saga pedo (p.54t,, Ephippiger provincial is (p.56), andvar ious chafer beet les (pp . 265-6) . Th is book is an in t roduc t ion and genera l gu ideto the i r iden t i f i ca t ion . Wi th i t s he lp , the genera l observer ought to be ab le to p lacethe major i t y o f insec ts tha t he d iscovers in the i r cor rec t fami l ies .The geograph ica l a rea covered by th is book is essent ia l l y wes tern Europe - wes to f a l ine f rom F in land to the nor thern shores o f the Adr ia t i c .

The se lec t ion o f insec tsto i l l us t ra te these, f rom a to ta l o f about 100,000 spec ies so fa r d iscovered inEurope, was no t a lways easy . Wi th in each group, we have chosen those rnos fl i ke ly to be no t iced , because o f the i r s ize , co lour , hab i ts , f requency , o r assoc ia t ionw i t h h u m a n h a b i t a t i o n .

But some qu i te ra reor loca l insec ts have been inc luded, s imp ly because they are so s t r i k ing tha t theycannot be over looked and a lways cause comment when they are seen. Examplesinc lude the Span ish Moon Moth (p . 139) and the longhorn beet le Rosa l ia a lp ina( p . 2 8 1 ) .The i l lus t ra t ions show most o f the insec ts in the i r na tura l res t ing pos i t ions , jus tas you migh t f ind them in the w i ld . Many spec ies can be ident i f ied per fec t l y we l lin th is way, bu t o thers need a c loser examinat ion o f the venat ion or perhaps o fthe h indwings . These are shown in the ' se t ' pos i t ion so tha t the re levant fea turescan be seen. Sexes are ind ica ted ( j = ma le , ! = female) on ly where they areconsp icuous ly d i f fe ren t . S izes are shown by magn i f i ca t ions pr in ted bes ide thei l lus t ra t ions : x2 /z mean ing tha t the p ic tu re i s rough ly 2Yzt imes l i fe -s ize . S izes dovary a good dea l , however , and the f igures are no more than rough gu ides .Where no magn i f i ca t ion is g iven , the insec t has been drawn a t approx imate lyl i fe -s ize .

    The tex t complements the i l l us t ra t ions , somet imes drawing a t ten t ion toimpor tan t d iagnos t ic fea tures or to fea tures on the unders ide tha t a re no t v is ib lein the p ic tu res . Co lour var ia t ions and sexua l d i f fe rences are ment ioned, andin fo rmat ion is g iven on behav iour , hab i ta t , and food-p lan t where these arehe lp fu l in iden t i f y ing an insec t . C lose ly re la ted spec ies can o f ten be d is t ingu ishedon ly by mic roscop ic examinat ion o f the gen i ta l ia and o ther minu te fea tures ,descr ip t ions o f wh ich are beyond the scope o f th is book . ln such ins tances , thecommonest spec ies are normal ly i l l us t ra ted and the tex t ind ica tes tha t there ares e v e r a l s i m i l a r s p e c i e s .There are br ie f in t roduc t ions to each insec t o rder and to the la rger fami l ies . Theseg ive the bas ic fea tures o f the groups and the ind iv idua l spec ies tex ts shou ld beread in con junc t ion w i th them. Many fami l ies a re represented here by s ing lespec ies , in wh ich case the name o f the new fami ly fo l lows tha t o f the spec ies .

  • Where no fami ly name is g iven , the insec t be longs to the same fami ly as thepreced ing spec ies .Eng l ish names are g iven as we l l as sc ien t i f i c names where poss ib le , bu t most o ft h e s m a l l e r a n d l e s s f a m i l i a r s p e c i e s d o n o t h a v e E n g l i s h n a m e s a n d t h e n o n l y t h esc ien t i f i c name can be g iven. Sc ien t i f i c names are recogn ised in te rna t iona l l y , bu tun for tunate ly tend to change as en tomolog is ts learn more about there la t ionsh ips o f the insec ts . Names found in one book are thus no t necessar i l y thesame as those found in o lder o r newer books . The names used here have beenbrought up to da te as fa r as poss ib le a t the t ime o f p r in t ing and show qu i te anumber o f changes f rom the f i rs t ed i t ion .T ime o f appearance is ind ica ted in f igures fo r the months dur ing wh ich the adu l tsmay be seen: e .g . 5 -8 means tha t the insec ts can be seen f rom May to August .These per iods app ly to the who le geograph ica l range o f the spec ies cohcerned,and the t ime o f appearance may be much more res t r i c ted in nor thern or montaner e g i o n s . O n l y a s i n g l e a n n u a l b r o o d m a y b e p r o d u c e d i n s u c h a r e a s , w h i l e i nwarmer par ts there may be two or even th ree broods in a year , w i th adu l ts inev idence fo r severa l months . Spec ies w i th no months g iven may be foundthroughout the year , a l though they may d isappear in to h iberna t ion in the coo le rreg ions .D is t r ibu t ion European d is t r ibu t ion is g iven in a s imp le fo rm:

    Southern areas are taken to be those rough ly south o f the Tees , bu t many spec iesl i s ted as southern w i l l obv ious ly have a more res t r i c ted d is t r ibu t ion than th is .There are , however , no hard and fas t d iv id ing l ines fo r insec t d is t r ibu t ions , manyof wh ich are imper fec t ly known, and spec imens may o f ten be found ou ts ide theind ica ted areas .Ear ly s tages .

Wehave, however , i l l us t ra ted a range o f them on pp . 294-5 ( te r res t r ia l ) and 296-7(aquatic), to provide a representative survey of the dif ferent forms,cross-referenced to and from the main part of the text.Other c reepy c rawl ies Insec ts be long to the phy lum Ar th ropoda ( ' jo in ted fee t ' ) ,wh ich a lso inc ludes cent ipedes , mi l l ipedes , wood l ice , mi tes , sp iders , and o therqu i te separa te c lasses o f inver tebra tes .

  • Insect AnatomyTechn ica l te rms are kept to a min imum in th is book , bu t some are unavo idab lewhen referr ing to various parts of insects' bodies and a basic knowledge of insectanatomy is necessary fo r iden t i f y ing many spec ies .The insec t body cons is ts o f th ree main par ts : the head. thorax , and abdomen.THE HEAD. The vertex is the area on top of the head, above and between the eyes.The cheeks (o r genae) a re the areas be low and beh ind the eyes , and the i r lowerpor t ions are somet imes d i f fe ren t ia ted as the jow ls . The head car r ies a pa i r o fan tennae or fee le rs , wh ich are main ly concerned w i th the senses o f smel l andtouch. The i r shape var ies a g rea t dea l , bu t in the i r s imp les t fo rm they are a cha ino f more or less ident ica l segments , each we l l supp l ied w i th nerve-end ings . Thenumber o f segments , rang ing f rom one to over a hundred, i s somet imes o f va luein ident i f y ing the insec ts . The f i rs t o r basa l segment i s the scape, and is o f tenlonger than the o thers . The second, usua l ly very shor t , i s the ped ice l , wh i le theres t together fo rm the f lage l lum. In some insec ts , such as the an ts , the scape ispar t i cu la r ly long and the res t o f the an tenna h inges upon i t . Such an an tenna isca l led e lbowed or gen icu la te .

    The head a lso has a pa i r o f compound .eyes , the i r sur faces c lo thed w i th a

    number o f t iny lenses ca l led face ts . Dragonf l ies and o ther ac t i ve f l ie rs havesevera l thousand o f these lenses in each eye, enab l ing them to de tec t very smal lmovements , bu t some o f the an ts and o ther so i l -dwe l le rs have very few lenses ornone a t a l l . Many insec ts a lso possess some very s imp le eyes ca l led oce l l i -usua l l y th ree , fo rming a l i t t le t r iang le on the ver tex o r somet imes on the f ron t o fthe head, and look ing l i ke t iny g lass

    The mouth is sur rounded by a number o f g rea t ly mod i f ied l imbs, co l lec t i ve lyknown as the mouth-par ts . The fo rm o f these appendages var ies enormous lywi th the insec t ' s d ie t , bu t the bas ic se t cons is ts o f a pa i r o f mand ib les o r jaws, apa i r o f max i l lae (somet imes ca l led secondary jaws) , and a lab ium or lower l ip ,fo rmed by the fus ion o f two max i l la - l i ke appendages. The max i l lae and lab iumhelp f i rs t to ca tch and ho ld the food wh i le i t i s cu t up by the mand ib les , then toshove l i t in to the mouth . They a lso have sensory a rms known as pa lps , wh ichexamine and taste the food f irst. Several other structures may be associated withthese mouth-par ts , no tab ly the labrum or upper l ip .

    WINGS are present in most insects, but not in the most pr imi t ive groups - thespr ingtai ls and br is t leta i ls (p. 16). They are also missing f rom a number of h ighlyspecia l ised parasi tes such as l ice and f leas (pp 98-101), and many high-al t i tudeinsects are wingless or virtually so. The 'typical' insect, however, has two pairs ofwings. Both pairs may be membranous, as in dragonf l ies and but ter f l ies, or the

    Insect life cyclesNearly al l insects begin l i fe as eggs. protected by tough, waterproof, and oftene legant ly scu lp tu red she l l s , these can surv ive a w ide range o f adverse cond i t ions ,from drought to severe frost. Many species pass the winter as eggs, often freelyexposed on the bare tw igs o f the i r food-p lan ts . Apar t f rom the pr im i t i ve w ing lessinsec ts (see p . 16) , the ha tch l ings ra re ly resemble the i r paren ts . They never havewings and often have quite dif ferent feeding habits. The considerable change thatthese young insec ts undergo as they deve lop is ca l led metamorphos is .

    L ike a l l o ther a r th ropods (see p 4) , insec ts have a tough ou ter ske le ton wh ichdoes no t g row wi th the res t o f the body and has to be changed per iod ica l l y fo r ala rger one. Th is sk in change is ca l led ecdys is o r mou l t ing . When about to mou l t ,the insec t s tops feed ing and becomes qu iescent fo r severa l hours o r even dayswhile the inner layers of i ts coat or skeleton are dissolved away. A soft, new,wr ink led sk in i s secre ted under the o ld layers , wh ich by now are very th in andbr i t t le . The insec t pu f fs i t se l f up by muscu lar ac t ion and by swa l low ing a i r o rwater to sp l i t the o ld sk in and to s t re tch the new one, and then s lowly d rags i t se l fou t o f the o ld sk in . The insec t i s espec ia l l y vu lnerab le un t i l the new sk in hashardened and most spec ies t ry to h ide themse lves when about to mou l t .

    When the new skin has become f irm, the insect gets r id of the excess air or waterand makes room fo r fu r ther g rowth . There is some e las t ic i t y in the sk in , espec ia l l yin ca terp i l la rs , bu t there comes a t ime when fu r ther s t re tch ing is imposs ib le andanother mou l t must take p lace . Some insec ts mou l t as many as 50 t imes, bu t th isis unusua l and most insec ts mou l t less than ten t imes. Most bu t te r f l y and mothcaterp i l la rs mou l t on ly four o r f i ve t imes.

No insect grows any more once i thas fu l l y -deve loped w ings , a l though mayf l ies do undergo one fu r ther mou l t inthe w inged s ta te (see p . 18) .

    Winged insec ts a re a r ranged in two d iv is ions , accord ing to the way in wh ichthe i r w ings deve lop . Among the dragonf l ies , g rasshoppers , bugs , and severa lo ther g roups , the w ings deve lop gradua l ly on the ou ts ide o f the body l These arethe EXOPTERYGOTA (= ou ts ide w ings) . The young resemble the adu l ts in genera lappearance, o f ten l i v ing in the same p laces and hav ing s imi la r feed ing hab i ts .The resemblance increases as the w ing buds ge t la rger a t each mou l t . There isthus a g radua l change f rom young to adu l t fo rm and the insec ts a resa id to showpar t ia l o r incomple te metamorphos is . The young are known as nymphs.

    Among the bu t te r f l ies and moths , beet les , f l i es , an ts , bees , wasps , and a fewother g roups , the young look no th ing l i ke the adu l ts , never showing any s ign orw ings and o f ten hav ing comple te ly d i f fe ren t homes and hab i ts . They are knownas la rvae. A t each mou l t un t i l the las t , they s imp ly emerge as la rger la rvae.

    Do not take a species year after year from the same local i ty. Local forms andspecies known to be rare should be col lected with the utmost restraint, andpreferably not at al l . *

    Leave the environment as you f ind i t : replace logs and stones after searchingbeneath them, and replace bark removed from dead t imber.

    Breeding from a fert i l ised female is better than taking specimens from the wild:unwanted specimens that have been reared should be released in the originallocality.
