Definition of eclose in English:

eclose

verbɪˈkləʊziˈklōz
[no object]Entomology
  • (of an insect) emerge as an adult from the pupa or as a larva from the egg.

    some larvae pupated and eclosed substantially earlier than average
    Example sentencesExamples
    • Older members of late summer populations are expected to have eclosed as relatively smaller adults because they developed under warmer temperatures and longer days during late spring/early summer.
    • Approximately 10-12 hr later, the two sides reappose and remain attached until the adult fly ecloses from the pupal case.
    • These ‘large larvae’ wander for an extended period before death, although rare escapers can progress to giant pupae that fail to eclose as adults.
    • Almost all of the rescued pupae eclose as adults and no aberrant pharate head structures are found.
    • Adult wasps eclosed within 1-3 days after arrival and were tested at ages of 5-11 days.

Derivatives

  • eclosion

  • noun ɪˈkləʊʒ(ə)nɪˈkloʊʒ(ə)n
    Entomology
    • In addition, developmental times to pupation and adult eclosion, pupal weights, and survival/mortality were measured for all insects.
      Example sentencesExamples
      • Discrete age estimates were used in conjunction with date of capture to estimate an approximate date of eclosion for each marked male.
      • Beetles with tolerant larvae also have higher numbers of eggs on eclosion and reduced longevity compared to strains and species with contest competition.
      • All of these results show that the pupal male was almost always killed by the already eclosed male immediately after, or even before, eclosion.
      • Aggression towards non-nest mates is provoked almost exclusively by chemical cues that are learned shortly after eclosion from the pupal life stage.

Origin

Late 19th century (as eclosion): from French éclore 'to hatch', based on Latin ex- 'out' + claudere 'to close'.
