2623 What in the good Lords name is this?
How's it going lads?

Just a quick one, I've got a young pear tree in my yard, noticed today some yellow/brown patches on some of the leaves, turned them over to find these hideous spikey growths on the back of them.

Does anyone happen to know what it is?

There's quite a few of them on different leaves in different parts of the tree. It's been very close to a peach and an apple tree but neither of those trees have these growths on them, so maybe it's specific to pear trees?

I'm not really an expert, but they're probably wasp eggs.

I thought wasps layed eggs in their nests?

But either way I wont be risking a wasp infestation, I'll be getting rid of these pronto

I think you've lucked out and got yourself a ferrero rocher tree by mistake.

Definitely looks like some kind of eggs, though I've not seen that kind before. The "growths" in >>2624 above the two brown spots in particular really look eggy. Whatever it is, scrap the leaves asap.

Gall wasps produce weird growths on leaves, but they look a bit different.

I have a feeling that's the galls/spore growths of Cedar-apple or quince rust, which affects apples and crabapples and other Rosaceae. Remove the affected twigs/leaves before it spreads any further and don't plant junipers and other Rosaceae near each other:

If you have some details of the sort of plant it is, you should check it against the records of the British Plant Gall Society.

Butterfly eggs, I think.

There are considerably more wasps then just the common wasp, it is an entire sub order of animals. Most of them don't form nests.

>>2631
I think this is most likely. They are probably the eggs of something that wants to eat the plant, hence why they aren't on anything else.

For my money, fig wasps are some of the weirdest things in nature.

The symbiotic life cycle is weird, makes you understand better the weird thoughts the Greeks had about where animals came from when you consider how obsessed they were with figs.

I'm personally more fascinated by the variants of parasitic wasp. Particularly the ones that subvert the natural cycle of plants by excreating chemicals turning the seeds and fruit into an armoured shell for them to live in. (If you've ever seen an oak tree drop those spikey wooden balls with their acorns. That is what those are).

I think we can all agree that wasps are proper wrong'uns.
