Photo of the week - Lady and the tramp


 
In amongst my vegetables, there are lots of little creatures going about their day. Just a little bit of patience is all it takes to get a glimpse into their busy world. My favourites to watch are the lady beetles, members of the family Coccinellidae. They are all rounded, most are yellow,orange or red, and have a number of spots on their wing-covers. In my garden, there are 2 common types: the small orange beetles with 2 large black blotches, and the larger yellowish beetles with many small spots.
 

Coccinella transversalis
 
"28-spotted Ladybeetle" Epilachna sumbana

The first is a friendly little fellow, and seems to hang about feasting on the occasional aphid or scale, or the mildew that grows on the leaves of my zucchini and squash. The second actually eats the leaves themselves. My simple rule of thumb for ladybeetles is: A few spots is good. Lots of spots is bad. If in doubt, I tend to think of Cruella DeVille. Even the babies don't look as friendly! See:

 
 
I'm sure in this case you can guess which is the unfriendly visitor just by looking, but if you were in your own garden, just have a look what they're doing. Beetles go through a number of larval stages so it's sometimes difficult to tell who is who, but the tell-tale scraping marks on the leaf are a good sign that this is a leaf-eating beetle.
 
The good news is that in general, they don't eat much. I don't spray the 'bad' insects at my place for fear of scaring off (or killing off) the good ones. If you have a healthy balance in your garden, a few nasty beetles aren't an issue and will only result in a few unsightly half-chewed leaves. Their populations can boom quickly if the weather is right, but birds generally catch up pretty quickly. I have a few larger shrubs and trees growing between the veg for insect hunters to gather in, and as they grow I'm seeing more birds all the time. As always, variety is the key!
 
 
And for those that are curious, my apple tree is still flowering away... sigh...
