  1. I'm a little surprised by this 1919 description of a parasitic #wasp (#Hymenoptera #Ichneumonidae), the only described species from #Australia in a genus that includes dozens of #species.

    The opening #Latin section gives rich detail on coloration and markings. The #English section describes morphology but has nothing about coloration. I would have expected the Latin to document a subset of the English, not to be fully complementary.

    Is this normal for some taxa?

  2. Four (parasitic) #wasps (#Hymenoptera) from a SLAM #Malaise sample in #Canberra #Australia over the last three weeks. Natural areas everywhere are (or should be) full of beautiful #insects like these, all just going about their business.

    A #FairyWasp in the genus #Mymar - the first I have seen here in the nominate genus - see how tiny this #insect is.

    An #ichneumon wasp (#Ichneumonidae) in the subfamily #Campopleginae - probably possible to get this one to genus, but most Australian species are unnamed.

    #Vosleria australia (or at least that's the only named Australian species in the genus) - family #Encyrtidae

    #Anastatus, unknown species - family #Eupelmidae

  3. Four more insects from the #Malaise trap, Canberra, ACT, 26 August to 2 September 2022

    1. #Ichneumoninae sp. - I'll key out at least the genus soon.

    2. #Orthocentrus sp. (#Ichneumonidae) - probably the commonest #ichneumon #wasp (or set of externally similar species) in my garden

    3. #Pentacladus eucalypti (a #BarkLouse #Elipsocidae)

    4. #Lamiinae sp. (a #LonghornBeetle #Cerambycidae) - I always find these harder to identify than I would expect

  4. Four #wasps from the #Malaise trap (Canberra, ACT) in the week of 19-26 August 2022.

    No close identifications yet, but these are 1) #Braconidae, 2) #Chalcididae: #Haltichellinae, 3) #Ichneumonidae: #Phygadeuontinae (should get that one to genus soon, but species likely to be unnamed), and 4) #Chalcidoidea.

    All on #iNaturalist if anyone wants to progress their identification:

  5. I ran a #Malaise trap run in my garden for two years (2020-10-23 to 2022-10-28). The first year's samples went to the Centre for Biodiversity Genomics in Guelph, ON for DNA barcoding. In the second year, I've been focused mostly on #Ichneumonidae and other parasitic wasps. #entomology

    Three insects from 12-19 Aug 2022: #Acanthobetyla cerbera (#Diapriidae, 2 images), #Elateridae sp. and probably #Anacis sp. (#Ichneumonidae).
