Time of year determines some, but not all, views of my blog posts

I was going to format this post as a spoof Nature communication, but not being as skilled as our students, who turn out excellently formatted mock papers for their assignments, decided not to. I did, however, go for a typical Nature title 🙂

The other day when I was looking at my blog stats I clicked on the view post stats button next to my most read post of the day, Not all aphids are vegans*, and was amused enough by the strong seasonal dynamics shown to post it on Twitter.

Not all aphids are vegans – strong seasonal dynamics

As you can see, the peaks and troughs of views strongly follow the times of year that aphids are present and absent.

As regular readers of my blog will know, I am a bit of an aphidophile. It is kind of hard to miss if I’m honest, but then aphids are fantastic and awesome, so you will get no apologies from me for loving them and writing, or talking about them whenever I get the chance to do so.

That said, not all my posts are about aphids, insects yes, but I do write about other things too, including entomological equipment, classic papers and teaching matters, and sometimes about my holidays 🙂

Given the strong correlation between aphid life cycle timing and visits to the post about biting aphids, I wondered how my other aphid posts stacked up in terms of seasonal viewing.

Aphid life cycles – bizarre, complex or what?

Somewhat surprisingly, well to me at least, the post about aphid life cycles did not show very strong seasonal dynamics, although April, when aphids start to become active, did, at the beginning of the post’s life, show a bit of a peak of interest, but has since broken down completely.  Another season aspect of aphid biology is wing formation. This is usually associated with late spring and early summer (Dixon, 1973, 1976), and in this case, the viewing history fitted appropriately.

Not all aphids have wings – seasonally appropriate


What about the other end of the year, autumn and winter?  As expected, my post about aphid overwintering showed the reverse pattern to the other aphid posts, people wanted to read about aphid overwintering as winter appraoched.

A Winter’s Tale – aphid overwintering

Aphid posts, as predicted, show a correlation (OK, not tested) with the time of year associated with the appropriate part of the life cycle.  We would therefore expect that posts that are more general would show no marked seasonality in their popularity. To test this I looked at first, my posts that deal with entomological equipment, pan traps, clip cages and the poster and then at two posts that fit into the teaching category.  Staring with the Pan trap, a very basic and commonly used piece of field equipment, despite a slight expectation on my part that there might be a spring peak (after all, that is when insects start flying) there was no pattern that I could see.

The pan trap – disappointingly no pattern


Nest I looked at the Pooter, an essential bit of general entomological kit (Leather, 2015) used by entomologists of all types. Given that this is used in both the laboratory and the field, I didn’t really expect to see any pattern jumping out at me.  I wasn’t disappointed although if you look very quickly, and not too closely, it is just about possible top convince yourself that there is an increase in views during the summer, which would fit with the general increase in insects caught in nets.

The Pooter – perhaps a slight tendency for views to increase in mid-summer


Next, back to aphids, this time a piece of kit that is almost, but not entirely, confined to aphidologists (Macgillivray & Anderson, 1957).  My expectation here, was that given that clip cages are almost always used in laboratories or glasshouses, that there would be absolutely no pattern in the viewing figures. Sure enough, that was the outcome.

The clip cage – no discernible patterns

Finally, the two teaching posts, first my tribute to Southwood’s classic species-area paper (Southwood, 1961).  I know that this post is used for undergraduate teaching at one university, so given the regularity of university timetabling, might have a chance of  showing a pattern;  It didn’t.

Southwood (1961) – the number of insect species associated with various trees – no pattern

Finally, a post that has attracted a modicum of attention over the years, all about what to expect in a PhD viva.  My hypothesis for this, given that most PhD projects start at the beginning of the academic year and run for four or five years before submission, was that if there was going to be an annual peak in views that it would be between October and January.  To save you the troubkle of squinting at the graph, there was no pattern.

Are PhD examiners really ogres? – no consistent peak

In conclusion, aphid posts tend to show viewing patterns consistent with the time of year and life cycle stage, other, more general posts show absolutely no pattern.

    Very entertaining and made me chuckle – thanks!

  3. I checked, and my post “Why goldenrods don’t make you sneeze: the biology of pollination” (https://scientistseessquirrel.wordpress.com/2015/09/03/why-goldenrods-dont-make-you-sneeze-the-biology-of-pollination/) does have the expected September signature. However, this is likely in part because I tweet a link to it every fall – I suppose I should set up an experiment in which I tweet a link to it in February and see if I can *remove* the temporal pattern!

  4. I should like to share with your readers a letter I am preparing for the Journal of Anecdotal Observations:
    “Leather (2020) and Ollerton (2020) have provided some support for the seasonality of the number of views of blog posts associated with insect behaviour. Here I provide further support for their hypothesis. A post on ivy bees (Colletes hederae) (https://wordpress.com/stats/post/1759/philipstrange.wordpress.com} on my blog shows strong seasonality, the number of views correlating (OK, not tested) with the emergence of Colletes hederae.
    I also noted another influence on the number of blog views, that is the effect of COVID-19 lockdown. My post on Cogden Beach (part of the Chesil Beach in west Dorset, https://wordpress.com/stats/post/1610/philipstrange.wordpress.com), concerned with the flora of this unusual isolated place, has for several years exhibited seasonality, peaking with the holiday season. The number of views was greatly increased following the easing of the COVID-19 lockdown in the UK. Perhaps this reflects the number of people avoiding foreign holidays but looking for interesting places to visit?”
