I is for Insect

There are a LOT of insects in the world. Some estimates put the number of living species as 30 million, only 900,000 of which have been described.  They are incredibly important to us – pollinating our crops, feeding us and other creatures, eating up poo- without insects we’d be neck deep in the stuff, breaking down wood and organic matter so that it becomes easy for bacteria to finish off the job and fertilise land for us to grow crops… their uses are legion, and not only that, some of them are exceedingly beautiful. Butterflies for instance – and dragonflies.

A lot of insects are very specialised. The loss of a single species could have far reaching effects as yet unknown to to us – for instance, a fly which lives on another fly could, if it dies out, mean that the first fly population gets out of control, causing problems like human diseases, or crops to be damaged.

We need insects.

Here is a fun poem – not about the dragonfly (although there is one of those in my book, Animal Magic) but one about the bombardier beetle. The bombardier beetle is an incredible creature.

It has a red thorax and legs and black wing cases and back. It has an extraordinary adaptation, two reservoirs of chemicals near the back tip of its abdomen, produced from glands inside. One reservoir contains hydroquinone and the other one hydrogen peroxide – when the beetle is threatened by a predator, it releases these chemicals with a popping sound, and they mix into a noxious, explosive, boiling hot spray which the beetle can control and direct with accuracy at its enemies killing them instantly.

Like most insects, because there are just so many of them, the bombardier beetle has not been assessed by the IUCN Red List, and its status is not known. However there are 3 ground beetles classified by the IUCN Red List as Near Threatened, Vulnerable and Critically Endangered, and one extinct.

Insects are becoming extinct every year – no-one knows how many, as they don’t know how many there are to start with. However a single tree in a rainforest, when examined, usually contains insect species unknown to science – and hundreds of acres of rainforest are cut down every day.

  1. It never fails to astonish me just how important insects actually are!


  2. I wouldn’t like to be on the wrong end of a bombardier beetle! You included some mind-boggling facts there, like what a small fraction we know about and that daily we are killing off animals that we never even knew about. I don’t think we give insects the credit they deserve!


    • Thank you for your comment, Nick, and THANK YOU, because you spelled bombardier correctly, which at half past midnight last night was clearly beyond me! My ‘r’ was missing.


    • Totally agree. Each has a role.

    My grandsons would love this one – it’s got the word “bum” in it!
    strangely, another blog I follow was on the insect theme – The Allotment Times.


    • I know and I am very proud that none of my poems have rude words in. BUT in this case – bum just has to be there. Couldn’t describe the animal without it!


  4. A great post; informative and entertaining. I’ve learnt something new today 🙂

    All the best


    • Thank you Jack! Sorry I didn’t reply, you were in spam. No idea why, you don’t appear to be trying to sell me software!


  5. That bombardier beetle sounds nasty, and almost mechanical.


    • It’s rather beautiful actually, and really only a menace to ants, although I wouldn’t want to be on the receiving end of those boiling chemicals myself!

    I know we need insects, but that doesn’t stop me from hating them!


    • Oh – they use to irritate me until I started reading about them!
