Superfamilies Tephritoidea and Sciomyzoidea (Dip- Tera: Brachycera) Kaj Winqvist & Jere Kahanpää
20 © Sahlbergia Vol. 12: 20–32, 2007 Checklist of Finnish flies: superfamilies Tephritoidea and Sciomyzoidea (Dip- tera: Brachycera) Kaj Winqvist & Jere Kahanpää Winqvist, K. & Kahanpää, J. 2007: Checklist of Finnish flies: superfamilies Tephritoidea and Sciomyzoidea (Diptera: Brachycera). — Sahlbergia 12:20-32, Helsinki, Finland, ISSN 1237-3273. Another part of the updated checklist of Finnish flies is presented. This part covers the families Lonchaeidae, Pallopteridae, Piophilidae, Platystomatidae, Tephritidae, Ulididae, Coelopidae, Dryomyzidae, Heterocheilidae, Phaeomyii- dae, Sciomyzidae and Sepsidae. Eight species are recorded from Finland for the first time. The following ten species have been erroneously reported from Finland and are here deleted from the Finnish checklist: Chaetolonchaea das- yops (Meigen, 1826), Earomyia crystallophila (Becker, 1895), Lonchaea hirti- ceps Zetterstedt, 1837, Lonchaea laticornis Meigen, 1826, Prochyliza lundbecki (Duda, 1924), Campiglossa achyrophori (Loew, 1869), Campiglossa irrorata (Fallén, 1814), Campiglossa tessellata (Loew, 1844), Dioxyna sororcula (Wie- demann, 1830) and Tephritis nigricauda (Loew, 1856). The Finnish records of Lonchaeidae: Lonchaea bruggeri Morge, Lonchaea contigua Collin, Lonchaea difficilis Hackman and Piophilidae: Allopiophila dudai (Frey) are considered dubious. The total number of species of Tephritoidea and Sciomyzoidea found from Finland is now 262. Kaj Winqvist, Zoological Museum, University of Turku, FI-20014 Turku, Finland.

Wallace Received: 8 March 2017; Accepted: 12 May 2017; Published: 18 May 2017 Abstract: Differences in growth rate of forensically important dipteran larvae make species determination an essential requisite for an accurate estimation of time since colonization of the body. Interspecific morphological similarities, however, complicate species determination. Muscle attachment site (MAS) patterns on the inside of the cuticula of fly larvae are species specific and grow proportionally with the animal. The patterns can therefore be used for species identification, as well as age estimation in forensically important dipteran larvae. Additionally, in species where determination has proven to be difficult—even when employing genetic methods—this easy and cheap method can be successfully applied. The method was validated for a number of Calliphoridae, as well as Sarcophagidae; for Piophilidae species, however, the method proved to be inapt. The aim of this article is to assess the utility of the MAS method for applications in forensic entomology. -

I have learned a lot from them, and I suspect the lessons (the ‘Kevin’ and ‘POM’ in my head) will keep on coming. Thanks guys!! Next, I would like to thank all of the members of the stalkie lab, and also, more recently, those of the Drosophila lab. The Ph.D. would not have happened without you – and that means all of you, really. Thanks!

Ejaculate Feeding and Female Fitness in The
ANIMAL BEHAVIOUR, 2005, 69, 489–497 doi:10.1016/j.anbehav.2004.03.018 Ejaculate feeding and female fitness in the sexually dimorphic fly Prochyliza xanthostoma (Diptera: Piophilidae) RUSSELL BONDURIANSKY, JILL WHEELER & LOCKE ROWE Department of Zoology, University of Toronto (Received 26 September 2003; initial acceptance 28 January 2004; final acceptance 25 March 2004; published online 18 December 2004; MS. number: A9711) Recent theory and empirical evidence suggest a role for sexual conflict in the evolution of male ejaculates, including ‘nuptial gifts’. According to the sexual conflict hypothesis, the greater the probability of female remating, the stronger the selection on males to induce an elevated reproductive rate in their mates, even if this reduces some components of female fitness, such as survivorship. Piophilid flies show an unusual form of nuptial gift: following copulation, females expel and ingest much of the sperm and accessory fluids received from the male. We investigated the effects of ejaculate ingestion on female fitness in the piophilid carrion fly Prochyliza xanthostoma by manipulating females’ opportunity to ingest the ejaculate under two background food levels (fed ad libitum versus starved). We also estimated females’ probability of remating. Few P. xanthostoma females mated more than once in repeated pairings with males. Females permitted to ingest the ejaculate oviposited sooner and laid more eggs than females prevented from ingesting the ejaculate, but ejaculate ingestion did not affect female survival. Hence, ejaculate feeding appeared to increase females’ net fitness. However, these effects were evident only in fed females, suggesting that ejaculate meals provide mainly stimulation rather than nutrition. The benign effects of ejaculate feeding on female fitness, and the lack of evidence of sexual conflict, are consistent with the low female remating rate in this species. -

As usual, I thank everyone for sending in such interesting articles. I hope you all enjoy reading it as much as I enjoyed putting it together. Please let me encourage all of you to consider contributing articles that may be of interest to the Diptera community for the next issue. Fly Times offers a great forum to report on your research activities and to make requests for taxa being studied, as well as to report interesting observations about flies, to discuss new and improved methods, to advertise opportunities for dipterists, to report on or announce meetings relevant to the community, etc., with all the associated digital images you wish to provide. This is also a great place to report on your interesting (and hopefully fruitful) collecting activities! Really anything fly-related is considered. And of course, thanks very much to Chris Borkent for again assembling the list of Diptera citations since the last Fly Times! The electronic version of the Fly Times continues to be hosted on the North American Dipterists Society website at http://www.nadsdiptera.org/News/FlyTimes/Flyhome.htm. For this issue, I want to again thank all the contributors for sending me such great articles! Feel free to share your opinions or provide ideas on how to improve the newsletter. -

Gases that built up inside the deceased and oozing fluids from the membranes were explained away as flesh eating vampires after a night’s feasting (they were bloated and full). Freshly culled meat became source to maggots and flies as it aged, transferring its ‘life force’ from one being into another (Sachs 2001). A mere century or two ago, Louis Pasteur would be the first westerner to directly link “moulds, mucors and bacteria” to that responsible of decomposition (this was just as the germ theory, that is, organisms smaller than the eye can see exist, was gaining acceptance.
