Why do we fear insects?

It makes sense to avoid insects which bite or sting, and to be careful not to let other insects like cockroaches and house flies walk all over the food we eat. We have an innate fear of some insects – especially the venomous ones. Some researchers suggest it is a defense mechanism, similar to our avoidance of snakes and large predators.

There is no need to be wary of all insects. As you will see in this video, pest insects and other insect species we should be wary of are in a minority. Most other insects are either beneficial insects, important in the environment, or harmless benign insects.

To save time, I have left out lots of insects that are beneficial. There are many species of beneficial flies such as hover flies, robber flies and tachinid flies. There are thousands of wasps which are beneficial as predators or parasites of other insects. I’ll have to make videos about some of these insects in the future!

I hope you enjoy the video! Please let me know in the comments.

A good start in life

One of the most vulnerable stages in an insect’s life cycle is the egg stage, or when larvae first hatch from eggs. What can adult insects do to ensure their young survive these sensitive stages?

Social insects such as ants, termites, and some bees and wasps are experts at protecting offspring. Their colonies are highly organised with a caste system made up of reproductives (fertile queens and males) and sterile workers. In a colonial structure such as this offspring are produced by the reproductives, and protected within the nest by workers. In other words the entire colony is focused on the well-being of the next generation.

Non-social insects have different strategies. Predatory wasps of the families Crabronidae, Sphecidae and Vespidae either construct mud nests or dig nest burrows. These wasps hunt for an insect or spider to sting and immobilise, then place it in the nest to lay an egg on. The hatching wasp larva will be safe and sound inside a well constructed nest (such as a mud nest), or a hidden nest (burrow), with plenty to eat. Check out this Sphex sp. (Sphecidae) wasp hauling a paralysed locust into a burrow she dug (below).

The Cherry Tree & The Meat Ant


This is a video about ants which visit my cherry tree. The story is primarily about meat ants (Iridomyrmex purpureus), but a couple of other species make cameo appearances. Why do the ants climb into my cherry tree? You’ll have to watch the video to find out!

I hope you enjoy the video – as usual, being ‘one minute bugs’, it’s short and sweet! Let me know what you think. Please hit the subscribe button in the widget if you would like to receive email alerts about new posts. The subscription process is more than one click, but it won’t take too long!
