Jon Sullivan<p>Yesterday I saw my 2nd "common" ectemnius, on a roadside near Lincoln, <a href="https://mastodon.nz/tags/NZ" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NZ</span></a>. This wasp is from Europe, Asia, & North America. It was first found in the southern hemisphere in Feb 2020 in Christchurch by Hannah Nolan, for her undergrad entomology collection at <a href="https://mastodon.nz/tags/LincolnUniversityNZ" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LincolnUniversityNZ</span></a>. It triggered a biosecurity response, and she passed the course.</p><p>There have now been 30 observations, all in and around Christchurch, as it slowly expands.</p><p><a href="https://inaturalist.nz/observations/266870319" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">inaturalist.nz/observations/26</span><span class="invisible">6870319</span></a></p><p><a href="https://mastodon.nz/tags/insects" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>insects</span></a> <a href="https://mastodon.nz/tags/wasp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>wasp</span></a> <a href="https://mastodon.nz/tags/BiologicalInvasions" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>BiologicalInvasions</span></a></p>
