<strong><em>Hyposoter placidus </em></strong>is one of the two common parasitoids hosted by the Small Copper butterfly (<em>Lycaena phlaeas). </em>This male emerged from a caterpillar found in early May on Baildon Bank, VC64.</div>
<div style="text-align: left;">
The caterpillar, which had been feeding on potted Sheep's sorrel, sought out a sheltered place underneath the pot where it became mummified before it could pupate.</div>
<div style="text-align: left;">
The adult Ichneumon emerged on 9th June 2013.</div>

A larva of Small Copper (<em><strong>Lycaena phlaeas</strong></em>) that I found feeding on Sheep's sorrel (<em>Rumex acetosella</em>) on Baildon Bank (VC64) has been the victim of a parasitoid attack.<br />
I can count seven woolly braconid cocoons underneath the larva and I suspect that these will belong to <em><strong>Cotesia cuprea</strong></em> (Lyle).<br />
It is gregarious, killing the host as a final instar larva, and sometimes reasonably common from the host (though the <em>Hyposoter </em>that mummifies the larva is often commoner). A brood in single figures would be quite unusual and they can sometimes number twenty or more.<br /><span></span>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2627017317786963649.post-46656172138527825042013-02-22T06:19:00.001-08:002013-02-23T07:36:56.289-08:00Aleiodes sp. near borealis<div class="separator" style="clear: both; text-align: center;">

On 1st February 2013 I found this mummified noctuid caterpillar attached to a gorse flower on Baildon Moor, VC64.<br />
This is likely to have played host to the parasitoid currently named <em><strong>Aleiodes borealis,</strong></em> which has a rather broad host range of moth larvae in the overwintering generation, especially <em>Xestia</em> and <em>Noctua </em>species.<br />
The RES handbook "CLASSIFICATION AND BIOLOGY OF BRACONID WASPS<strong>"</strong> (Shaw & Huddlestone) states that "<em>In most cases the host is killed when only partly grown </em><em>and the mummy is stuck to the foodplant (or often another substrate, following a well </em><em>characterised behavioural change by the stricken host) by mean of a gluey fluid </em><em>through an antero-ventral slit cut in the host integument by the fully grown parasitoid </em><em>larva</em>".

<em><strong>Dolichogenidea breviventris</strong></em> (Ratzeburg) (= <em>Apantales mesoxanthus</em> (Ruschka)) is a known parasitoid of <em>Coleophora serratella</em> and I found three examples in July and August 2012 emerging from <em>serratella</em> cases found on birch in Baildon and Esholt, West Yorkshire, VC64.<br />
