|The braconid wasp Apanteles glomeratus - adult|
I appear to have both males and females, although the females are more numerous, as you might expect (female Ichneumonids are usually self-fertile). Both measure 3mm long, excluding antennae. There are 32 in the sample.
So we have a few interesting numbers resulting from this sample:
- Pupation period of the wasp is around 21 days.
- One fully-grown larva of the Large White can support 32 wasp larvae.
- A few of the wasp cocoons have not (yet) hatched. Perhaps these are parasitised and will emerge later.
I was a bit surprised that they emerged so quickly, since there are very few Large White larvae around at this time of year, so I presume they must overwinter a hibernators, ready to restart the parasitization cycle when the first batch of Large White larvae hatch next year.
