FAQs

  • What is the collective noun for a group of stick insects

    Stick insects are not social creatures, so there is no collective noun!

  • I have a seen a large stick insect with a smaller stick insect on its back. Is it a baby or mating?

    Stick insects do not show any level of parental care (apart from the fact that some species selectively position their eggs). This will almost certainly be a mating pair, the male being the smaller individual that is on top.

  • Are there any UK native Phasmids?

    There are several species of phasmid that have become naturalised in the UK. This topic is discussed in more detail here: UK Phasmids. If you find stick isnetcs in the UK you can report them using our online phasmid recording form.

  • Can you eat Phasmids?

    Some indigenous people do use Phasmids as a food, notably Stone (1992) reports Extatosoma tiaratum is eaten by natives of Papua New Guinea (although as E. tiaratum is not found in this region the author probably refers to Eurycantha or Extatosoma popa). The insects eat the leaves of the sago palm, which are used as a thatching material.

  • How many eggs do phasmids lay?

    The largest recorded amount of eggs laid by a single female is 2,052 by Acrophylla titan, 89 per week on average (Brock, 1999). Phasmids generally lay between 100 and 1000 eggs.

  • How long do Phasmids live?

    Adults may live from several weeks to a few years. Males generally have a shorter lifespan than females. Males of Phyllium bioculatum often only live for around three weeks as adults. Dares verrucosus may have a lifespan of up to five years (Brock, 1999).

  • What is the longest phasmid?

    At the moment the longest described species is Phobaeticus chani. For me details please see: The World's Longest Insect.

  • What is the heaviest phasmid?

    Females of Heteropteryx dilatata are the heaviest known Phasmids. A female laden with eggs may weigh in excess of 65g (Brock, 1999). The heaviest recorded specimen at a PSG meeting (belonging to Kristien Rabaey and Rob Simoens) weighed in at 49.2g (Smith, 2007), but culture stocks are likely to be significantly smaller than wild specimens are.
