/ˈprəʊnɪmf/, U.S.

/ˈproʊˌnɪmf/

Origin: Formed within English, by derivation. Etymons: pro- prefix², nymph n.¹

Etymology: < pro- prefix² + nymph n.¹

Entomology.

1. In certain holometabolous insects (e.g. sawflies): an individual in a distinct larval or prepupal stage in which larval tissue is broken down and adult tissues begin to be formed within the larval cuticle.

ΚΠ

1895 D. Sharp in Cambr. Nat. Hist. V. 164 The process of forming the various organs goes on in the pronymph, till the ‘nymph’ has completed its development.

1925 Ann. Entomol. Soc. Amer. 18 175 The larva finishes its cocoon, then become motionless... The larva by this time has passed into the state of the pronymph... A constriction is noticed at the fifth joint and becomes accentuated until the moment when the larva casts its skin and passes into the prepupal condition.

1955 Ecology 36 64/2 The following developmental stages were also noted; eonymph, pronymph, pupae..and unemerged adults.

1994 Entomologia Experimentalis et Applicata 70 105 There are two types of prepupae in diapause in the soil, the eonymph and the pronymph.

2. In hemimetabolous insects: an individual in the stage of late embryonic development immediately preceding the moult into the first nymphal instar, which in some groups (e.g. dragonflies) persists for a brief period after hatching from the egg . Cf. nymph n.¹ 3a.

ΚΠ

1920 E. M. Walker in Ann. Entomol. Soc. Amer. 13 138 Mantoidea. Diurnal, solitary.., hatching as a pronymph; number of moults 7 or 8.

1949 C. Longfield Dragonflies Brit. Isles (ed. 2) 30 The tiny nymph on hatching first appears as a ‘pro-nymph’ encased in a transparent skin like a parcel in cellophane.

2001 G. C. McGavin Essent. Entomol. 84 The pronymph is an embryonic stage and moults to the first nymph as it hatches from the egg.

1895 D. Sharp in Cambr. Nat. Hist. V. 164 The pronymphal state may be looked upon as being to a great extent a return of the animal to the condition of an egg.

1949 C. Longfield Dragonflies Brit. Isles (ed. 2) 30 The pro-nymphal cuticle is retained until the nymph has wriggled itself into the water.

2002 Ann. Rev. Entomol. 471 In many hemimetabolous insects, such as cockroaches, lice, and true bugs.., the pronymphal cuticle is shed during hatching and the insect emerges from the shell as a first stage nymph.
